android: camera_device: Only advertise RAW support if RAW16 is available
The Android camera2 API defines a RAW capture capability ([1]) for
devices that support "outputting RAW buffers and metadata for
interpreting them". This capability requires the camera device to
support RAW_SENSOR ([2]) as an output format. Despite what its name may
sound like, the RAW_SENSOR format is defined as a 16 bits RAW format,
not an opaque implementation-dependent format (which is instead called
RAW_PRIVATE). Devices may additionally support the RAW10 and RAW12
formats, but that isn't enough to claim RAW capture capability.
To comply with the API requirements, only report the
ANDROID_REQUEST_AVAILABLE_CAPABILITIES_RAW capability when 16-bit RAW is
supported.
