drm/msm/sde: update rpmh solver state during idle state

Display RSC driver might receive bandwidth updates during
idle power collapse if new frame prepare has higher or
lower bandwidth requirement. Current RSC driver
informs mailbox driver that solver mode is disabled
during idle state. That may lead BUS driver to send
WAKE & AMC TCSs during idle state. This may lead to
hardware hang because pdc is in sleep state. Avoid such
hang by updating mailbox state to solver state in
idle state.
