soc: qcom: mdtloader: Add PAS context aware qcom_mdt_pas_load() function
Introduce a new PAS context-aware function, qcom_mdt_pas_load(), for
remote processor drivers. This function utilizes the PAS context
pointer returned from qcom_scm_pas_ctx_init() to perform firmware
metadata verification and memory setup via SMC calls.
The qcom_mdt_pas_load() and qcom_mdt_load() functions are largely
similar, but the former is designed for clients using the PAS
context-based data structure. Over time, all users of qcom_mdt_load()
can be migrated to use qcom_mdt_pas_load() for consistency and
improved abstraction.
As the remoteproc PAS driver (qcom_q6v5_pas) has already adopted the
PAS context-based approach, update it to use qcom_mdt_pas_load().
