occ: Fix Pstate ordering for P9
In P9 the pstate values are positive. They are continuous set of
unsigned integers [0 to +N] where Pmax is 0 and Pmin is N. The
linear ordering of pstates for P9 has changed compared to P8.
P8 has neagtive pstate values advertised as [0 to -N] where Pmax
is 0 and Pmin is -N. This patch adds helper routines to abstract
pstate comparison with pmax and adds sanity pstate limit checks.
This patch also fixes pstate arithmetic by using labs().
