Add the SoC-level display subsystem nodes for Shikra: MDSS wrapper,
DPU display controller, DSI host controller, and 14nm DSI PHY.
Shikra uses DPU 6.5 hardware (same as QCM2290). Platform-specific
compatible strings are used as the primary match with QCM2290 fallbacks
to reuse the existing driver support.
The dispcc clock inputs for the DSI byte and pixel PLLs are wired
from mdss_dsi0_phy.

Don't blindly copy bits and pieces from other platforms. No, its' not
QCM2290.

Enable the Shikra MDSS display subsystem on the Shikra CQM EVK
board and add the DLC0697 MIPI DSI display panel node.
Pin pm4125_l5 to 1.232V with regulator-allow-set-load
for DSI PHY PLL stability.

AVEE is typically the negative / ground supply. How can it be supplied
by the same regulator as AVDD?

I think, recent recommendation is to sort these entries by the pin

send broken workaround which is in clear violations of coding style and
DT spec.
That's a poor way to upstream things. Just throwing the code over the wall.
