Subject: [PATCH v2 0/7] remoteproc: qcom_q6v5_pas: Add support for QDU1000/QRU1000 mpss

This patchset adds support for the mpss found in the QDU1000 and QRU1000
SoCs. 

The mpss boot process now supports late attach for an already running
mpss. For this, it uses an RMB register space to perform a handshake
with the mpss for the late attach process. This is implemented in the
patches below. The patches also address issues with split binary
detection to support loading of split binaries more robustly.

Changes from v1:
* Dropped changes to aoss-qmp
* Renamed mpss pas bindings
* Updated commit msg on mdt loader to be more descriptive
* Fixed syntax errors in bindings
* Updated firmware name in bindings
