arm: Add support for a preram_cbmem_console symbol.

This symbol is set using a config variable which can be set to something
appropriate by the SOC. If it isn't, the symbol is set to 0 which should be
caught by checks in the cbmem console itself.

TEST=Built for nyan with a cbmem buffer location set. Built for peach_pit
without a location set.
