Algy Tynan af88d65e86 mimxrt: Add ALT11 pin mode support for MIMXRT1176.
This adds support for the ALT11 alternate function mode on MIMXRT1176
MCUs, enabling FLEXPWM channels on GPIO_AD pins that were previously
unavailable for PWM use.

Changes:
- Add PIN_AF_MODE_ALT11 enum to pin.h
- Add ALT11 column to MIMXRT1176_af.csv with FLEXPWM mappings
- Enables FLEXPWM1-4 on GPIO_AD_06 through GPIO_AD_21

This change only affects MIMXRT1176-based boards (MIMXRT1170_EVK and
PHYBOARD_RT1170). Other MIMXRT family chips use alternate function
modes ALT0-ALT9 and are not affected.

Tested on MIMXRT1176 hardware with PWM output on GPIO_AD_14
(FLEXPWM3_PWM0_X).
