msm: footswitch-8x60: Reset DSI domain along with MDP collapse/restore

Some DSI-related logic lives in MDP's collapsible GDHS domain for
8960, 8064 and 8930. Assert the reset to this domain when the reset
of MDP is reset. Use of the reset-only clocks added here assumes the
display driver is making sure the DSI clocks (not managed by the
clock driver) are enabled for the duration of the collapse and
restore sequences so that the resets propagate.

msm: clock-8960: Move DSI resets functionality to their own clocks

The DSI core resets are currently associated with the DSI byte clocks
because the DSI core clocks are managed by the DSI driver directly,
not the clock driver. Move the reset functionality out of the byte
and into their own reset-only branch clocks so that the footswitch
driver, which needs to assert these resets, can do so without
involving the unrelated byte clock.
