Use GUSBCFG_FORCEHOSTMODE to detected the HOST forced mode as it is done
in the Linux driver drivers/usb/dwc2/core.c:dwc2_core_reset().
The host polling must be executed only if the current mode is host,
either due to the force HOST mode (which persists after core reset)
or the connector id pin.
The GUSBCFG_FORCEDEVMODE bits is used to force the device mode (for
example used on STM32MP1x platform) and when it is activated the DWC2 reset
failed with the trace:
"dwc2_core_reset: Waiting for GINTSTS_CURMODE_HOST timeout"

When the usb node is defined dr_mode="otg" ehci_usb_phy_mode() is called
to determine the mode from status registers.
The IMX95RM does not currently define the USBNC STATUS register but it is
assumed to be an omission as the first three registers are defined.
It has been expirimentally verified that the USBNC_PHY_STATUS register
at offset 0x23C bit4 (USBNC_PHYSTATUS_ID_DIG) reads 0 when USB_ID is GND
and 1 when floating.
Use is_imx9() as this driver works for i.MX91, i.MX93 and i.MX95 and all
of these determine the role based on the USBNC_PHY_STATUS register.

Add initial support for i.MX95 USB.30 PHY, which is similar to
the i.MX8MQ and i.MX8MP USB PHY.
The i.MX95 USB3 PHY has a Type-C Assist block (TCA) consisting of two
functional blocks (XBar assist and VBus assist) and is documented
in the i.MX95 RM Chapter 163.3.8 Type-C assist (TCA) block.
Instead of relying on an external MUX for Type-C plug orientation the
XBar can handle the flip internally.
Add initial support for i.MX95 by:
- allowing the driver to be enabled i.MX95
- resetting the XBar
- configuring the TCA in System Configuration mode (which was determined
to be necessary to enable the PHY in device-mode)
Follow-on support will need to be added to steer the XBar based on
either board design (if only one pair is brought out) or if used with a
Type-C controller.

The driver currently does:
mtd->dev->parent = cadence->dev;
This works in Linux because `struct mtd_info` embeds a `struct device`,
so `mtd->dev` is always valid and its `.parent` can be set.
In U-Boot, however, `mtd->dev` is only a pointer to a `struct udevice`.
Dereferencing it before assignment is invalid, which breaks the device
hierarchy. As a result, consumers relying on `mtd->dev` (e.g. partition
parser, reset and re-init paths) operate on a dangling pointer. This
leads to failures during warm reset when the NAND device is accessed
again.
Fix by assigning the device pointer directly:
mtd->dev = cadence->dev;
This matches U-Boot’s device model, preserves a valid hierarchy, and
resolves the warm reset issue on Cadence NAND.

Fix PHYTEC EEPROM bus mismatch between SPL and U-Boot proper by enabling
CONFIG_SPL_DM_SEQ_ALIAS=y on phyCORE-i.MX93 boards. This way, both the
SPL and U-Boot proper will respect the device-tree aliases for I2C devs
and use the same I2C bus number for phytec_eeprom_data_setup() function
calls. This makes code less confusing and more robust.
Fixes an issue apparent since commit 79f3e77133bd ("Subtree merge tag
'v6.16-dts' of dts repo [1] into dts/upstream") where SPL would spew the
following error:
phytec_eeprom_read: i2c EEPROM not found: -110.
phytec_eeprom_data_setup: EEPROM data init failed
While later in U-Boot proper, EEPROM would be successfully read out.
This happens because Linux device-tree for phyBOARD-Segin-i.MX93 since
aforementioned commit enables I2C bus 2 (lpi2c2 is used for audio codec
and RTC) which breaks SPL I2C bus number ordering and I2C EEPROM bus is
shifted by +1. Now, lets prevent this from happening again by utilizing
device-tree aliases also in the SPL.

On i.MX9 platforms, when booting from USB, the U-Boot environment is
always assumed to be in RAM. However, this causes the boot to hang when
`CONFIG_ENV_IS_NOWHERE` is not enabled. The boot also hangs even if the
environment is present in another storage media (for example, eMMC). Fix
the issue by correctly handling the U-Boot environment's location when
booting from USB. Also for i.MX95, set the environment location based on
the ENV config and not solely based on the boot device type.

The existing compatible name for U-Boot's k3 system controller driver
i.e "ti,am625-system-controller" has been added to linux[1] device-tree.
This compatible in kernel is meant for configuring the Control Module
registers (CTRL_MMR0).
However in U-Boot, the matching driver was being used to load the system
firmware on the secure M-cores by the R5 SPL and therefore must be
updated to a different compatible to avoid conflicts.
Therefore, this patch renames all references of the compatible to
"ti,am654-tisci-rproc-r5". The "-r5" is appended so as to avoid any
future conflicts since r5 specific compatibles should only be useful for
U-Boot.

serial_find_console_or_panic() may left cur_serial_dev unassigned if
REQUIRE_SERIAL_CONSOLE is not set. Setting GD_FLG_SERIAL_READY in
this situation confuses serial console code. It tries to use
unassigned driver instead of debug port and stops printing.
So check cur_serial_dev before setting GD_FLG_SERIAL_READY to allow
console to keep printing via debug port.
