mainboard: Drop print_ implementation from non-romcc boards

Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*. Back in the day, like more than
half a decade ago, we migrated a lot of boards to printk, but we never
cleaned up the existing code to be consistent. instead, we worked around
the problem with a very messy console.h (nowadays the mess is hidden in
romstage_console.c and early_print.h)
This patch cleans up the mainboard code to use printk() on all non-ROMCC
boards.
