7638235311 feat(mcpwm): MCPWM event comparator driver
In esp32p4, the MCPWM has a new feature, mainly ETM-oriented.
Each operator has two event comparators, can generate an event
when the count value of the timer that operator connects is equal
to the value of event comparator.

fc80d3e568 feat(mcpwm): Set group clock prescale dynamically
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.

5ab755915b feature(MCPWM): Add MCPWM trigger driver and test
Each MCPWM operator has two Trigger (named T0 and T1), and they can be
routed to GPIO fault signal or timer sync event.Generator can be set up
to perform different action on Trigger event.
This commit add a trigger driver and a test for the driver.

72d0f5b35b mcpwm: can't apply the same delay module to multiple generators
This is a hardware limitation, one delay module can only be used by one generator at one time.

f0bea3ce51 mcpwm: support not reset GPIO config at exit
By default, the driver will reset the GPIO used by the MCPWM capture
channel at exit. But in some special use cases, the same gpio may also
be used by another device, which shares the same gpio configuration,
resetting the gpio is not expected.
