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.
