[U-Boot] [PATCH v4 00/22] imx: vybrid: Update BK4 and PCM052 boards to only use DM/DTS

This patch series converts PCM052 and BK4 to use Driver Model and Device

Some notable changes:
- The way how MAC address is read from fuses can now be adjusted
- DTS improvement/sync with kernel (also extract u-boot specific properties)
- Using generic code instead of one from board

The output of u-boot boot:

U-boot master branch: SHA1: b1b1bab7f92b838a252ab977f56d9c3584c14fb7

Changes in v4:
- Fix maming of DDRBYTE0 -> DDRBYTE2 (as it is in the documentation)
    - Update DDRBYTE0 -> DDRBYTE2 as in VF610 user manual

Changes in v3:
- Add code to enable I2C0 code as suggested by Stefan (so the code can be
  reused by other boards without regressions)
- Exclude the pcm052.c related code to a separate patch
- New patch (separate board code patch)

Changes in v2:
    - Rename pcm052.dts to vf610-pcm052.dts
    - Rename bk4r1.dts to vf610-bk4r1.dts
    - Extract 'u-boot,dm-pre-reloc;' property to separate file (to facilitate
      sync with Linux kernel dts files)
        - New patch
        - Disable EFI related support and commands (as we do not plan to
          use EFI on this setup)
