Drop McASP AFIFOs for all AM62 based platforms, as the extra buffering
is not needed with BCDMA already having internal buffering.
Also fix the pinmux for McASP1 on AM62P.

Changes in v2:
- Drop [tx|rx]-num-evt properties instead of setting to 0
- Add Fixes tag for am625-phyboard-lyra-rdk
- Link to v1: https://lore.kernel.org/r/[email protected]

McASP AFIFOs are not necessary with UDMA-P/BCDMA as there is buffering
on the DMA IP. Drop these for better audio latency.

On SK-AM62P, McASP1 uses two pins for communicating with the codec over
I2S protocol. One of these pins (AXR0) is used for audio playback (TX)
so the direction of the pin should be OUTPUT.

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.
