UserPD firmware image is loaded and booted by ath12k driver. Get the userPD
memory region from DTS and load the firmware for userPD from pre-defined
path into io-remapped address of this region. Authenticate this image
using pasid which is a peripheral ID. Set the spawn bit to instruct Q6
to spawn userPD thread. Wait for userPD to spawn which is indicated by
spawn interrupt. Ready interrupt is triggered once the userPD is powered
up completely.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
