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.
