LiPPERT FrontRunner-AF [1/2]: create board by forking AMD Persimmon

Step 1: copy all files unmodified from Persimmon.  This makes it much
easier later to see how the two boards actually and deliberately differ
when porting bugfixes from one to the other.  Git's copy detection is
imperfect (and slow).

+ * after the decision about S3 resume is made, and before the system tables are
+ * written into RAM.	The routine that is responsible for writing the tables is
+ * "write_tables", called near the end of "hardwaremain".	There is no platform
+ * specific entry point between the S3 resume decision point and the call to
+ * "write_tables", and the next platform specific entry points are the calls to
+ * the ACPI table write functions.	The first of ose would seem to be the right
+ * place, but other table write functions, e.g. the PIRQ table write function, are
+ * called before the ACPI tables are written.	This routine is called at the beginning
+ * of each of the write functions called prior to the ACPI write functions, so this
