mdss: fix dynamic FPS mode switch configuration



For dual DSI panels, DFPS mode switch configuration through
sysfs is not properly enabled for the second DSI interface.
Fix this by initializing the mode switch update variable.

While changing the DFPS mode, idle-time should be disabled
and the device should be configured to default FPS. Add
these checks when DFPS mode switch is initiated.
