media: video: tegra: tegra_camera: re-arch power and clock
There are a couple of issues found in tegra_camera.
1. clock enable/disable is controlled by user space.
-> If client process crashes, there is no way to disable clock.
2. power enable/disable is associated with clock enable.
-> There is no reason to relate power with clock.
-> There is only one regulator for this driver.
-> As same as #1, it may leave power up when client process crashes.
3. driver allows multiple clients to access.
-> This is not the case for this driver.
This changes addresses the problems described above.
