media: qcom: camss: Use common VFE pm_domain_on/pm_domain_off where applicable

Browse source 
For the various versions of VFE we have a boiler-plate
pm_domain_on/pm_domain_off callback pair of the general form.

- Error check.
  Not always done but applicable to all.

- device_link_add (DL_FLAG_STATELESS | DL_FLAG_PM_RUNTIME |
                   DL_FLAG_RPM_ACTIVE);

- Error check returning -EINVAL on error.

- Return 0

Reduce the pattern down to a common callback. VFE 4.1 is a special case
which to me also indicates that it is worthwhile maintaining an indirection
for the vfe_pm_domain_{on|off} for now.

Otherwise lets chuck out a bunch of needlessly replicated code.
