[v4,0/3] Improve K3-am625-sk support (USB, MMC)

Message

This series picks up a few patches from the TI BSP tree that
unfortunately didn't make it upstream thusfar.

The first patch improve SD card compatibility (allowing U1 class cards
to be used), the remaining ones add USB support.

The type-c connector isn't entirely modelled with these changes as
it goes through a TPS6598 PD controller. Unfortunately the dtb bindings
for that currently require an irq line, which is not connected on E1 and
E2 version boards. The patchese to support this setup unfortunately didn't land
yet[0].. As such the last patch ignored the PD controller and simply
configures usb0 as periphal only rather then mode switch capable, which
at least gives some basic usability of that USB port.

Changes in v4:
- Disable new usbss nodes by default in the dtsi and enable in the dts
- Drop unneeded disabled nodes in board dts

Changes in v3:
- Rebased against current ti-next aka 6.2-rc1
- Add Martyn's tested-by

Changes in v2:
- Rebase against linux-next 20221220

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
