meson64: current (5.10.y): ODROID N2(+) patchset rework for mainline u-boot, stability and rebootability (#3154)
- starting from Home Assistant OS (HASSOS) setup/patchset, which is stable with pure-mainline
  - *huge thanks* to Stefan Agner (@agners) from Home Assistant for his work and help with this
  - CONFIG_DRM_MESON=y fixes the order of shutdown callbacks, allowing it to reboot without patches
    - this increases the kernel size a bit, due to some dependencies like DRM=y
    - remove the shutdown revert patch, allowing other meson64 boards to mainline-reboot
  - add fdt/no-map patch fixing the dreaded "SError Interrupt on CPU4" panics that plagued the N2
- move the N2 to mainline u-boot on current (rebased, already done)
  - add SPI-enabling DTB variants, which allow writing to SPI NOR flash (and usage instructions in comments)
    - add UBOOT_TARGET_MAP and write_uboot_platform_mtd to current, for nand-sata-install to SPI/USB goodness
  - remove the UHS-enabling patch, to avoid 1.8v vs 3.3v mess. Make sure to use only A1-rated SD cards as recommended.
- change default cpufreq governor for 24h+ stability
- other patch cleanups:
  - move deprecated/non-applying patch to need-check
  - remove the HardKernel ODROID-specific reboot driver and DTS patches (odroid-reboot.c) which are now useless.
  - remove documentation-only patches (we have enough patches in meson64 without those)
  - remove duplicated SAR ADC patches
  - remove multiple different and conflicting patches for DTS and emulated-PWM GPIO fan
    - now using simple on/off GPIO fan at 30 celsius, unrelated to passive cooling

Subject: [PATCH 7/9] arm64: dts: meson: add uart_A node
The UART_A is available through J3 pin 8/10 and documented to be
available as UART by default.
