AM62 has 3 ECAP instances with 1 APWM each. Add DT nodes for the same.
Keep them disabled in am625-sk dts as these pins can be repurposed in
user exp connector.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/1] arm64: dts: ti: k3-am625-sk: Add ECAP APWM nodes
commit: bd67e1be98ddb884ff3f3df95c2382e6e70930b6
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.
