[PATCH] Be silent in ram_check in non-debug loglevels

[Mart Raudsepp]

As DBE61 support now runs ram_check for non-debug purposes and has expected failures
on DBE61A, downgrade the per-address looped fail notification printk and other messages
from BIOS_ERR to BIOS_DEBUG.
Document that if something is wanted to be reported in non-debug loglevels, one should
do so in the caller based on the return value.
Tweak a debug string in ram_verify to be more descriptive.
