usbdebug: Make the EHCI debug console work in the bootblock
Currently this needlessly initializes the hardware in the both the
romstage and the bootblock, but it works.
Build option is renamed to USBDEBUG_IN_PRE_RAM to reflect the
use better, related support files can be built to pre-ram stages
regardless of usbdebug being enabled or not.
Tested on Google/peppy (adapted to C_ENVIRONMENT_BOOTBLOCK).
