The get hw version and src pad code functions can be common code in csid
core file, then the csid driver of different hw version can reuse them,

Is it also the case with csid-4-1 and csid-47 that the HW version is in
the format x.x.x - because you're removing this printout which just
prints the register in favour of a later function that decodes that
register into three parts.
Suggest having a csid_hw_version_gen1() for these two and a
csid_hw_version_gen2() which does the x.x.x print instead.
=> camss-csid-4-1.c and camss-csid-4-7.c will have hw_version =
csid_hw_version_gen1()
=> camss-csid-gen2, camss-csid-790 will have hw_version = hw_version_gen2()
