[PATCH RFC 10/10] arm64: dts: qcom: sm6125-xiaomi-ginkgo: enable display, backlight and touchscreen

["YİĞİTCAN KAVAKLI via B4 Relay" <devnull+kavakliyigitcan.gmail.com@kernel.org>]

From: YİĞİTCAN KAVAKLI <kavakliyigitcan@gmail.com>

Enable the display subsystem (MDSS/MDP/DSI0), Kinetic KTD3136 backlight,
and Novatek NT36672A SPI touchscreen on the Xiaomi Redmi Note 8 (ginkgo).

Hardware nodes added:
- Fixed LCDB regulators (lcdb_lab and lcdb_ibb at +/- 5.5V)
- MDSS and DSI0 with Tianma 1080x2340 FHD+ video panel
- I2C1 backlight node at 0x36 with PMI632 GPIO 6 hardware enable
- SPI2 touchscreen node at CS0 with GPIO 88 interrupt and panel follower
  reference
- Touchscreen active pinctrl definition on GPIO 88
