Subject: [PATCH 10/13] media: qcom: camss: Add sm8550 compatible

Add CAMSS_8550 enum, sm8550 compatible and sm8550 camss drvier private
data, the private data just include some basic information now, later
changes will enumerate with csiphy, csid and vfe resources.

Also add a default case in vfe_src_pad_code to get rid of a compile
warning since a new hw enum is added.

  drivers/media/platform/qcom/camss/camss-vfe.c:291:10: warning:
  enumeration value 'CAMSS_8550' not handled in switch [-Wswitch]
    291 |         switch (vfe->camss->res->version) {
        |                 ^~~~~~~~~~~~~~~~~~~~~~~~
