ARM: S5P: Extend MIPI-CSIS platform_data with the PHY control callback

Browse Source 
Extend MIPI-CSIS driver's platform data structure with a callback
for D-PHY enable and reset control. Also add a flag indicating
whether the external MIPI-CSI (VDD18_MIPI) power supply should
be managed in the driver through the "vdd" power supply. On some
boards this regulator may be a fixed voltage regulator without
an inhibit function.
