feat(mcpwm): Set group clock prescale dynamically

Browse Source 
MCPWM group clock pre scale was originally fixed to 2, which is
inconvenient. Set group clock prescale dynamically. Now the maximum
resolution of the MCPWM timer is up to 160MHz(when the prescale set
to 1). And add a resulotion config for MCPWM capture.
