clk: qcom: gdsc: Manage clocks with !CONFIG_PM

With CONFIG_PM disabled, turn the devices clocks on during
driver binding to the device, and turn them off when the
driver is unbound from the device. Platforms can specify
all the clocks that need to be managed in !CONFIG_PM case
using qcom_pm_add_notifier().

The use of pm_clk_add_notifier() isn't appropriate here since we need
to only manage clocks with valid power domain associations done via
DT, instead of what pm_clk_add_notifier() does, which is manage clocks
for all on SoC/off SoC devices associating all of them to a dummy power
domain instead
