fsp_baytrail: update to add the UPD_MEMDOWN_CHECK macro 

- Update chipset_fsp_util.h to add the UPD_MEMDOWN_CHECK pointing into
the PcdMemoryParameters structure.  This is baytrail FSP specific, so
it's put into the chipset code instead of the 'driver' code.  Since some
of the values need to be decremented and some do not, a second parameter
was added to control this.  This macro also does not print out the
values as they are printed out separately if memory down is enabled.
- Update chipset_fsp_util.c to use the UPD_MEMDOWN_CHECK macro.  This
makes the code more standardized and easier to read.
