[PATCH v3 0/3] rockchip: rk35xx: Implement checkboard() to print SoC variant

[Jonas Karlman]

Information about what SoC model and variant can be found in OTP. This
series use this information in checkboard() to print out the running
SoC model and variant, should match what is printed on the SoC.

There are some asumptions taken on how some of the OTP values are
encoded, however for my boards this seem to match and something like
one of the following is shown with this applied:

  SoC:   RK3566
  SoC:   RK3566T
  SoC:   RK3568
  SoC:   RK3568B2
  SoC:   RK3568J

  SoC:   RK3582
  SoC:   RK3588
  SoC:   RK3588S
  SoC:   RK3588S2

  SoC:   RK3308B
  SoC:   RK3308B-S

Changes in v3:
- Fix build issue with MISC=n or ROCKCHIP_OTP=n
- Remove use of cpu-version
- Use log_debug() instead of debug()

Changes in v2:
- Drop changes in generic-rk35xx_defconfig
- Update code comments
- Add patch for rk3308

This can probably be converted into an sysinfo driver in a future series,
once other pending changes to sysinfo core have settled.
