Arthur Heymans be9533aba9 nb/intel/gm45: Add C_ENVIRONMENT_BOOTBLOCK support
The i82801ix_early_init is now called both in the bootblock and
romstage. The rationale behind setting this up twice is to ensure
bootblock-romstage compatibility in the future if for instance VBOOT
is used.

This moves the console init to the bootblock.

The romstage now runs uncached. Adding a prog_run hooks to set up an
MTRR to cache the romstage will be done in a followup patch.

The default size of 64KiB is not modified for the bootblock as trying
to fit both EHCI and SPI flash debugging needs a more space and 64KiB
is the next power of 2 size that fits it.

TESTED on Thinkpad X200.
