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.

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.

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.

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.
