Force single-threaded access to HWPs in PRD
Hostboot does not support thread local storage, however several
HWPs use this concept. Specifically the memory HWPs use it for
their c_str() function that prints out target strings. If these
HWPs are called in multiple threads there is a chance of a buffer
overrun that leads to a crash.
The fix is to create a new INVOKE-style macro that befores the
same mutex lock as a regular FAPI_INVOKE_HWP call.
