Drop per-board ram_check() calls for now.

Drop per-board ram_check() calls for now.

Every board had a slightly different invokation, very often commented out
anyway. We could either decide that this is only to be used by developers
during bringup (and thus added manually to romstage.c and removed before
the board gets committed). This method seems to be preferred from what I
have heard on IRC / mailing list in the past.

Or, we add the ram_check() somewhere globally and allow the user to enable
it via menuconfig (possibly only if EXPERT is selected).

Either way, the current method of spreading the calls all over the place is
not really the way to go.
