Introduce the debounce select mux macros to allow folks to setup
debounce configuration for pins. Each configuration selected maps
to a specific timing register as documented in appropriate Technical
Reference Manual (example:[1]).

Changes since V1:
- I have'nt picked up Krystoff's ack since the file modified is now different.
- Changes now applied to k3-pinctrl.h instead of the ABI header that is
now set up to be deleted in v6.5-rc1.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/1] arm64: dts: ti: k3-pinctrl: Introduce debounce select mux macros
commit: 0bec3d7ecc7493b0e530f6f34539841ef6779006
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.
