remoteproc: qcom_q6v5_pas: Unload lite firmware on ADSP

The UEFI loads a lite variant of the ADSP firmware to support charging
use cases. The kernel needs to unload and reload it with the firmware
that has full feature support for audio. This patch arbitarily shutsdown
the lite firmware before loading the full firmware.
