drm/msm/dsi: Use single function for reset
There is currently two function for performing reset: dsi_sw_reset and
dsi_sw_reset_restore. Only difference between those is that latter one
assumes that DSI controller is enabled. In contrary former one assumes
that controller is disabled and executed during power-on. However this
assumtion is not true mobile devices which have boot splash set up by
boot-loader.
This patch removes dsi_sw_reset_restore and makes dsi_sw_reset disable
DSI controller during reset sequence if it's enabled.
