drivers/intel/fsp*: Use newly added post codes for memory param prep
This change replaces use of post codes 0x34 and 0x36 in fsp drivers to instead use POST_MEM_PREINIT_PREP_{START,END} to make it easy to search from where these post codes are generated during boot flow. Additionally, it adds POST_MEM_PREINIT_PREP_END to fsp2_0 memory_init to make it consistent with fsp1_1 memory init.
