Subject: [PATCH] mediatek: update mt7987 SoC device tree

mt7987b.dtsi:
  Enabled lvts (for CPU thermal) and trng by default.
  Remove non-existent netsys include headers, fix build.

mt7987.dtsi:
  Remove unused rt5190a include headers
  Fix pwm-fan errors: binding cdev pwm-fan to trip 3 failed: -22

Fixes: 9de7189ed ("mediatek: build image for MT7987 RFB")
Signed-off-by: Chukun Pan <amadeus@jmu.edu.cn>
