[RFC PATCH] arm64: dts: qcom: glymur-asus-zenbook-a16: Describe BOB1 and the IR emitter

[Jesse Casco]

PMH0101 BOB1 feeds the PM8010 camera LDOs and the PMH0101 flash module.
Describe it, and wire the IR illuminator: flash channels 1 and 4 ganged,
350 mA torch, 700 mA flash, attached to the HM1092 via flash-leds.

Values:
- channels 1+4, 350 mA torch, 700 mA flash, 1280 ms timeout: Windows
  LEDFLASH configuration (FlashLED_1)
- BOB1 3.384-3.512 V: within the AOP OTP limits for B1B_E0
  (3.296-3.520 V); BOB2 is not populated

Konrad, this goes on top of your A16 PM8010 and IR camera commits in
qcom-laptops; feel free to fold it in. Tested on a 7.3 kernel with the
same DT: ir:flash probes with no faults and lights the HM1092 scene.
