J7200 has 7 I2Cs in main domain, 2 I2Cs in MCU and 1 in wakeup domain.
Add DT nodes for the same.

Add DT nodes for I2C GPIO expanders on main_i2c0 and main_i2c1 and
also add the pinmux corresponding to these I2C instances.

Hi Vignesh Raghavendra,
I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/2] arm64: dts: ti: j7200: Add I2C nodes
commit: afc0406bd8a797d8d5066e935eb7c098cf9449de

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.
