console: Drop driver list in ramstage

Browse Source 
This framework was only available in ramstage. So we had to define
console output functions separately for bootblock, romstage and SMM.
Follow-up patches will re-enable all the consoles removed here,
in a more flexible fashion, and with less lines-of-code and copy-paste.

Also the driver list is not in a well-defined order and some of the
loops could exit without visiting all drivers.

NOTE: This build has no console in ramstage.
