media: ccs: Differentiate SMIA and MIPI vendors in static data

Browse source

MIPI CCS uses a 16-bit MIPI manufacturer identifier for firmware filenames
compared to older 8-bit identifier used by SMIA. The requested firmware
files used the MIPI manufacturer ID even for SMIA compliant devices,
effectively making the manufacturer ID 0.

While CCS static data is a feature of CCS 1.1, it has no hardware
dependencies. Making this feature available for SMIA devices helps adding
support for them and avoids requesting ill-generated CCS static data file
names. The files are named as:

	ccs/smiapp-module-vv-mmmm-rrrr.fw,
	ccs/smiapp-sensor-vv-mmmm-rr.fw and
	ccs/smia-sensor-vv-mmmm-rr.fw

where vv is the manufacturer ID, mmmm is the model ID and rr or rrrr is
the revision number.
