Subject: [PATCH v1 0/2] dw-mipi-dsi: add power on & off optional phy ops and update stm

These patches fix a bug concerning an access issue to display controler (ltdc)
registers.
If the physical layer of the DSI is started too early then the fifo DSI are full
very quickly which implies ltdc register's access hang up. To avoid this
problem, it is necessary to start the DSI physical layer only when the bridge
is enable.
