[PATCH v10 07/14] soc: qcom: mdtloader: Remove qcom_mdt_pas_init() from exported symbols

[Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>]

qcom_mdt_pas_init() was previously used only by the remoteproc driver
(drivers/remoteproc/qcom_q6v5_pas.c). Since that driver has now
transitioned to using PAS context-based qcom_mdt_pas_load() function,
making qcom_mdt_pas_init() obsolete for external use.

Removes qcom_mdt_pas_init() from the list of exported symbols and make
it static to limit its scope to internal use within mdtloader.
