west: updated hal_nxp for updated LPC PWM definitions

Updated the west.yml file
to add nxp_hal update for pwm
definitions used by devices
LPC5534, LPC5536 and LPC55S36.
The nxp_hal changes lets the PWM
driver be aware that these devices
contain a WAITEN bit in their PWM
register which can be used when setting
up the PWM on init phase.
