mchp: PWM add MEC172x and clean up
Add MEC172x PWM support and clean up the hard coded PWM PCR
numeric values with PWM PCR register defines for (SZ) 144 pin
parts. MEC1701, MEC152x, and MEC172x 144 pin parts have 9 PWM's.
MEC152x and MEC172x have 4 TACH's. MEC1701 has 3 TACH's.
BRANCH=none
BUG=none
TEST=Build MCHP MEC170x and MEC152x boards
