src/*/post_code.h: Change post code prefix to POSTCODE

The prefix POSTCODE makes it clear that the macro is a post code.
Hence, replace related macros starting with POST to POSTCODE and
also replace every instance the macros are invoked with the new
name.

The files was changed by running the following bash script from the
top level directory.

header="src/soc/amd/common/block/include/amdblocks/post_codes.h \
	src/include/cpu/intel/post_codes.h \
	src/soc/intel/common/block/include/intelblocks/post_codes.h"

array=`grep -r "#define POST_" $header | \
	tr '\t' ' ' | cut -d ":" -f 2 | cut -d " " -f 2`

for str in $array; do
	splitstr=`echo $str | cut -d '_' -f2-`
	grep -r $str src | cut -d ':' -f 1 | \
		xargs sed -i'' -e "s/$str/POSTCODE_$splitstr/g"
done
