Unlike imx6, on imx7 the USB PHY is described as:

	usbphynop1: usbphynop1 {
		compatible = "usb-nop-xceiv";
		clocks = <&clks IMX7D_USB_PHY1_CLK>;
		clock-names = "main_clk";
		#phy-cells = <0>;
	};

which does not have the 'reg' property.

Do not return an error when the 'reg' property is not found
for the USB PHY.

This fixes USB gadget regression on a imx7s-warp board.

Successfully tested the "ums 0 mmc 0" command on two boards:
imx7s-warp and imx6dl-pico-pi.

On a imx7s-warp board the fdtdec_get_alias_seq() function
always fails.

As priv->portnr is only used on i.MX6, move fdtdec_get_alias_seq()
inside the CONFIG_MX6 block.

When `usb start` is called on the terminal, the dwc2 driver will try
to start every USB device as host first, even if it is explicitly
configured as peripheral in the device tree (dr_mode = "peripheral").

So to avoid an unwanted 15 seconds delay when initializing the usb
(one second per channel = 1s x 15), this patch adds a check to the
initialization, and will skip host initialization of the device is
explicitly set as peripheral. The checking is already done similarly
in the `drivers/usb/gadget/dwc2_udc_otg.c` driver.

For systems which use generic PHY support and implement USB PHY driver,
the parsing of PHY properties is unnecessary, disable it.

According to EHCI spec, software needs to do handshake with HC for
safely removing QH from async list. This handshake is implemented by
setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD
register and poll the IAA (Interrupt on Async Advance bit) in the
USB_USBSTS to ensure the HC has released all on-chip state that may
potentially reference one of the data structures just removed.

Current codes only check active status of the last QTD, but this can't
ensure the QH is released from HC. We can meet unrecoverable
"EHCI timed out on TD" errors when running UEFI SCT tests on USB disk.
The USB_ASYNCLISTADDR register is changed to a invalid address when the
issue happens. It is fixed after adding the IAA handshake.

Steps to reproduce the issue:
1. Build the UEFI SCT from https://github.com/tianocore/edk2-test
2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2
3. Copy SCT files and Shell.efi to USB disk FAT partition
4. Load the Shell.efi from USB FAT, and run bootefi to execute it
5. After booting into Shell, enter the SCT directory and run "sct -a"
   to execute all tests.
6. Tests run about 1 hour and stop with many EHCI timeout errors like
   EHCI timed out on TD - token=0x801f8c80

The iMX8M uses nop PHY, select PHY and NOP_PHY automatically.
Otherwise, the DM capable driver is now perfectly compatible.

Fix cast from pointer to integer of different size by casting the
pointer to uintptr_t instead of uint32_t, the former has correct
size on both 32bit and 64bit architectures.
