drivers/intel/fsp2_0: Use DECLARE_REGION for FSP-M heap

There are 2 ways of referring to linker symbols, as extern
u8[] or extern u8*. Only the former will be correctly
initiated into an immediate operand (a constant) to asm.

DECLARE_REGION defines reference in form of extern u8[].
Use DECLARE_REGION as a standard way for these references.
