media: qcom: camss: Pass remainder of variables as resources

Browse Source 
The following variables are being assigned statically based on
compatible strings in the probe path.

* enum camss_version version;
* unsigned int csiphy_num;
* unsigned int csid_num;
* unsigned int vfe_num;
* unsigned int vfe_lite_num;
* unsigned int vfe_total_num;

Migrate those variables to resource parameters passed in on platform
probe arguments. The one caveat is for VFE it has been necessary to
intoduce a new variable vfe_total_num to capture the aggregate value of
vfe_num + vfe_lite_num.

All the rest of the changes are rote camss->variable to
camss->res->variable with the parameter tables now populating the listed
variables.
