The gpio-expander on i2c-1 has a maximum frequency of 100kHz. Update our
main_i2c1 frequency to allow the nxp,pcf8574 gpio-expander to function
properly.

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

[1/3] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Lower I2C1 frequency
      commit: 9c316d58c238e58d6346458462e8b0fd308e7332
[2/3] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Add HDMI support
      commit: bac441710306a84c52f0f9a561aa9839b91caa14
[3/3] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Remove HDMI Reset Line Name
      commit: fecdf6de7e47849504d0edaaff55fa0baadef420

For future reference: using a cover-letter (though not mandatory)
helps reviewers provide a ack/ other tag on cover letter to apply to
all patches and b4 can easily figure it out.

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.
