media: qcom: camss: Remove special case for VFE get/put
From sdm845 onwards we need to ensure the VFE is powered on prior to
switching on the CSID.
Currently the code tests for sdm845, sm8250 and then does get/set. This is
not extensible and it turns out is not necessary either since vfe_get and
vfe_set reference count.
Remove the over-conservative SoC version check.
