Fix vdd_log to support a new Micron DDR4

Merged Kamil Trzciński requested to merge fix-vdd-log into master

I tested:

  • It can boot Manjaro
  • It appears to set vdd_log to max 1V
  • It can boot my Ubuntu when SDcard is inserted

What was not tested:

  • If it works with all possible RAMs
  • If it works with Android SDCard
