Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.
After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on analog devices.
V4L/DVB (9977): Kbuild: fix compilation when dib7000p is not defined
dib7000p.h defines a few extern symbols when CONFIG_DVB_DIB7000P is not set. since the
header is used on more than one driver, this causes symbol duplication, as pointed by

V4L/DVB (9973): v4l2-dev: use the release callback from device instead of cdev
Instead of relying on the cdev release callback we should rely on the
release callback from the device struct. This requires that we use
get_device/put_device to do proper refcounting. In order to do this
safely v4l2-dev.c now sets up its own file_operations that call
out to the driver's ops.

Use a consistent crystal value of 28.636360 MHz for computing all PLL

set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded. Also fixed I2S Master clock dividers.
