hwpstate_amd(4): Revamp the softcHEADmain

As the new CPPC and old P-states modes are exclusive, put their
respective data in a union.

Rename the field containing the content of the CPPC_REQUEST register.
It it now to be accessed using 'cppc.request'.

Use an 'unsigned int' instead of 'uint32_t' for 'flags'.  This is an
internal field whose width could be changed at will.  We only have one
flag at the moment.

No functional change intended.
