[nrf noup] boards: nordic: Add PWM support for LEDs on nRF54 DKs

Adds support for first possible LED to be connected with HW PWM. Upstream PR: zephyrproject-rtos/zephyr#72010 Merged as noup because of conflicts. Signed-off-by: Karol Lasończyk <[email protected]> (cherry picked from commit 382a1ee791e3637b5b7d25f22905017c24997438)
