Update SB800 CIMX FADT

- Add #define to allow the FADT PM Profile to be overridden.
 - Change the location of the PMA_CNT_BLOCK_ADDRESS to match
   current documentation.
 - cst_cnt should be 0 if smi_cmd == 0
 - add a couple of default access sizes.
 - Add a couple of #define values for unsupported C2 & C3 entries.
 - Add PM Profile override value into amd/persimmon platform.
   This does not use the #defines in acpi.h so that the files that
   include this don't all need to start including acpi.h.
