[PATCH] arm64: dts: ti: k3-am64-main: Remove support for HS400 speed mode

[Aswath Govindraju]

AM64 SoC, does not support HS400 and HS200 is the maximum supported speed
mode[1]. Therefore, fix the device tree node to reflect the same.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/1] arm64: dts: ti: k3-am64-main: Remove support for HS400 speed mode
      commit: 0c0af88f3f318e73237f7fadd02d0bf2b6c996bb

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.
