media: qcom: camss: vfe-17x: Rename camss-vfe-170 to camss-vfe-17x

vfe-170 and vfe-175 can be supported in the same file with some minimal
indirection to differentiate between the silicon versions.

sdm845 uses vfe-170, sc8280xp uses vfe-175-200. Lets rename the file to
capture its wider scope than vfe-170 only.
