platform: mipi: Do not reset DSI PHY before clock off

DSI PHY was getting reset before disabling the DSI clocks.
This fixes issues where the DSI interrupts were
not getting cleared properly, causing bootup hangs in kernel
This also fixes cases where the DSI clocks were not completely
shutting down if continuous splash feature is turned off.
