Normally clk_vote_vdd_level() and clk_unvote_vdd_level() are called
while holding the clock framework's prepare_lock since they are called
in the prepare paths. However, we're also calling clk_unvote_vdd_level()
from qcom_cc_sync_state() when removing proxy votes. This happens
outside of the clock framework, so the prepare_lock isn't protecting
this case. If the sync_state callback fires while another thread is
voting/unvoting voltage from a normal clock call, then there's a race
condition that can result in regulators being set to the incorrect
voltage or being pre-maturely disabled.
Add a mutex to protect this case.

Currently GSI endpoint usb_request pointer is allocated only once
during boot time and it used by dwc3 driver for mapping doorbell register
address with USB endpoint request only once. During composition switch
or connect/disconnect scenarios same USB endpoint is being re-enabled and
does not create mapping again.
On some platforms multiple UDC cores can work in device mode. In case
of binding the UDC with primary controller first and then disconnect the
primary and bind UDC to secondary controller. Driver does not re-mapping
the doorbell address with current UDC core and USB GSI wrapper is trying
to access previously mapped GSI DBL address with previous core
resulting into smmu fault.
Fix this issue by adding re-mapping of doorbell using dwc->sysdev node
to map the doorbell register with correct UDC.
