Printing coreboot debug messages on VGA console is pretty much useless, since

Browse Source 
initializing VGA happens pretty much as the last thing before starting the
payload. Hence, drop VGA console support, as we did in coreboot v3.

- Drop VGA and BTEXT console support. 
  Console is meant to be debugging only, and by the time graphics comes up
  99% of the risky stuff has already happened. Note: This patch does not remove
  hardware init but only the actual output functionality. 

  The ragexl driver needs some extra love, but that's for another day
- factor out die() and post()
- drop some leftover RAMBASE < 0x100000 checks.
