drm/msm/dsi: Reset both PHYs before clock operation for dual DSI
In case of dual DSI, some registers in PHY1 have been programmed
during PLL0 clock's set_rate. The PHY1 reset called by host1 later
will silently reset those PHY1 registers. This change is to reset
and enable both PHYs before any PLL clock operation.
