[PATCH v2 0/2] Add SPI display support for UNIHIKER M10 V1.2

[Miotsuki Mizuno <founder@crepuse.com>]

Add the panel compatible and enable the SPI2 display using the existing
panel-mipi-dbi driver. This series depends on the separate common I2C2
board preparation patch in this review package, but not on NS2009.

The external initialization firmware is available at:
https://github.com/mio-tsuki/panel-mipi-dbi-firmware/releases/tag/v1.0.0
Required filename: dfrobot,unihiker-m10-display.bin
SHA256: 50412ae6d29c5bbfb7fac585528a761fb249d7944011a1b19c5e0f80a0418e5f

Changes since v1:
- Normalize author/sender identity and preserve it in each patch body.
- Check every patch in both ordinary and strict modes with the binding
  present when checking the DTS compatible.

The binding and DTS diffs are unchanged. Prior physical display tests
passed RGB565 patterns, direction and partial/full updates. Register
readback showed a 100 MHz input with BAUDR=2 for 50 MHz transfers; no
oscilloscope measurement is claimed. Reset ACTIVE_HIGH was physically
verified. The nominal active area is represented as 43 x 58 mm.
