When building the NVIDIA out-of-tree drivers against 3rd party Linux
kernels where V4L2 support is not be enabled by default, the camera
drivers fail to build. Although this is expected, it is preferred that
the driver can still be built but then fail when loaded. Update the
camera drivers to guard around the V4L2 functions so that the drivers
can still be built but will return an error where needed.

kernel drivers can be built as built-in (=y) or module
(=m). The old ways of checking a driver is enabled or
not is to use "#if define(CONFIG_XXX)" for built-in and
"#if defined(CONFIG_xxx_MODULE)" for module.
Switch to the new IS_ENABLED() macro which can check
a driver is configured as built-in or module.
