Update hex values to CBFS binary name types in Makefiles

These binaries were being added to CBFS using hexadecimal values instead
of the CBFS binary type names.  The same value was being used in
different places for different things.
For example, the value 0xAB is used for SPDs, MRC & FSP binaries.

This patch uses CBFS type names instead of hex values everywhere a
hex value was previously used.
