Move BL_COHERENT_RAM_BASE/END defines to common_def.h

We have lots of duplicated defines (and comment blocks too).
Move them to include/plat/common/common_def.h.

While we are here, suffix the end address with _END instead of
_LIMIT.  The _END is a better fit to indicate the linker-derived
real end address.
