The SDM845 MSS needs the load_state powerdomain voted for during the
duration of the MSS being powered on, to let the AOSS know that it may
not perform certain power save measures. So vote for this.

With rpmh ARC resources being modelled as power domains with performance
state, we need to proxy vote on these for SDM845.
Add support to vote on multiple of them, now that genpd supports
associating mutliple power domains to a device.

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.
