[PATCH] arm64: dts: ti: k3-am62x-sk-common: Add bootph-all for I2C1 instance pinmux

[Devarsh Thakkar]

I2C1 controller controls io-expander which provides power to voltage
regulator vdd_mmc1 for MMC SD using a gpio line.

Add bootph-all to the pinmux node for this instance, as this is used during
SPL stage too by the bootloader while using SD boot mode as without this
the SD boot mode fails with below error when using this device-tree in
u-boot:

"Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured

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

      commit: 175133a32b48a092363828ce3041a0adaab01ffc

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.
