[PATCH 1/2] clk: qcom: camcc-sdm845: Fix topology around titan_top power domain

[Vladimir Zapolskiy <vladimir.zapolskiy@linaro.org>]

On SDM845 two found VFE GDSC power domains shall not be operated, if
titan top is turned off, thus the former power domains will be set as
subdomains by a GDSC registration routine.

Fixes: 78412c262004 ("clk: qcom: Add camera clock controller driver for SDM845")
