ARM: tegra: Device tree changes for v6.15-rc1

This contains a few patches that add some missing, display-related nodes
on Tegra114 and Tegra124, as well as a small fix in the display clock
used for DSI on Tegra114 and the addition of a light sensor found on the
ASUS TF101.

* tag 'tegra-for-6.15-arm-dt' of https://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  ARM: tegra: tf101: Add al3000a illuminance sensor node
  ARM: tegra: Add DSI-A and DSI-B nodes on Tegra124
  ARM: tegra: Add HDA node on Tegra114
  ARM: tegra: Add ARM PMU node on Tegra114
  ARM: tegra: Switch DSI-B clock parent to PLLD on Tegra114
