firmware: qcom_scm: Add SHM bridge handling for PAS when running without QHEE

On SoCs running with a non-Gunyah-based hypervisor, Linux must take
responsibility for creating the SHM bridge both for metadata (before
calling qcom_scm_pas_init_image()) and for remoteproc memory (before
calling qcom_scm_pas_auth_and_reset()). We have taken care the things
required for qcom_scm_pas_auth_and_reset(). Lets put these awareness
of above conditions into qcom_scm_pas_init_image() and
qcom_scm_pas_metadata_release().
