Start split and complete split tokens need the hub address and the
downstream port of the first HS hub (device view).
The core of the function was duplicated in both host/ehci_hcd and
musb-new/usb-compat.h.

This driver is meant to be used with any OHCI-compatible host
controller in case if there's no need for platform-specific
glue such as setup of controller or PHY's power mode via

With the old order of initialization the hcor pointer has been setup to
the same address as Exynos EHCI base address (0x12110000 instead of
0x12110010).
Such behaviour was caused by reading value of 0 instead of 0x10 from EHCI
HCCPBASE register without doing proper clock initialization before.
To fix this problem hcor initialization has been moved after USB PHY setup.
Now ehci_readl(&ctx->hcd->cr_capbase) returns correct value.

As per dwc3 databook, delay is required before taking the core out of reset.
This delay is required so that the PHY are stable, and then we can take core
out of reset.
Reference is taken from linux dwc3 code, file: drivers/usb/dwc3/core.c.

When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.
Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.

This patch enables the USB EHCI support for the Marvell Armada XP (AXP)
SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure
the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done
this already in the bin_hdr (SPL U-Boot). Without this, accessing the
controller registers in U-Boot or Linux will hang the CPU.
Additionally, the AXP uses a different USB EHCI base address. This
patch also takes care of this by runtime SoC detection in the Marvell
EHCI driver.

USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.
Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.
This patch removes the powering off calls, fixing the undesirable power
bouncing.
Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs
to be measured - should be close to 700MHz (1.4G/2).
Note that some freqs aren't in the PLLU table in T210 TRM
(13, 26MHz), so I used the 12MHz table entry for them. They
shouldn't be selected since they're not viable T210 OSC freqs.
Since there are now 2 new OSC defines, all tables (pll_x_table,
PLLU) had to increase by two entries, but since 38.4/48MHz are
not viable osc freqs on T20/30/114, etc, they're just set to 0.
