7dd8ade24d remoteproc: qcom: q6v5-mss: Add custom dump function for modem
The per segment dump function is responsible for loading the mba
before device memory segments associated with coredump can be populated
and for cleaning up the resources post coredump.

0304530ddd remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequence
Refactor re-useable parts of mba load/unload sequence into mba_load and
mba_reclaim respectively. This is done in order to prevent code duplication
for modem coredump, which requires the mba to be loaded before dumping
the segments. The following changes in functionality are intended:

* Add software bypass to avoid high MX current in mpss error path.
* Remove the proxy votes of clk/regs only after the active/reset clks/regs.
* Reclaim MBA memory after mpss_load failure in mba_reclaim func.
* Set/Unset the dump_mba_loaded flag on mba_load/mba_reclaim respectively.

bbcda30271 remoteproc: qcom: q6v5-mss: add SCM probe dependency
The memory ownership transfer request is performed using SCM, ensure
that SCM is available before we probe the driver if memory protection is
needed by the subsystem.

Assign the relocated base of the modem image, as the offsets
from the virtual memory might not be based on the physical
address.

ef73c22fa0 remoteproc: qcom: Rename Hexagon v5 modem driver
The qcom_q6v5_pil implements support for the self-authenticating modem
subsystem. With the introduction of other q6v5 based non-TZ based
remoteproc driver the current name is cause for confusion, so rename it
to be more specific.

No functional change.
