Camera: OOT: Add T264 specific PMC calls

Browse Source 
For Tegra264, new PMC driver is introduced to support instance specific
driver data. As per the design, on Tegra264, if client drivers are using
below PMC exported APIs, they need to pass their struct device pointer
as an argument. Also it is expected that clients dt node should have
"nvidia,pmc" property populated with appropriate PMC instance phandle.
 - *_io_pad_power_enable()
 - *_io_pad_power_disable()
