Any attempt to enable titan_top_gdsc on SM8550-QRD fails and produces
an error message that the gdsc is stuck at 'off' state.
However if MMCX power domain is simply replaced to MXC one, it allows
to turn titan_top_gdsc on successfully, even if MMCX is remained off
according to /sys/kernel/debug/pm_genpd/pm_genpd_summary report.
Note that at the moment qcom,sm8450-camcc.yaml gives a definite comment
that the supply power domain should be MMCX, and it may be needed in
some certain cases, but at the moment they are not unveiled on SM8550
platform.
