Bjorn Andersson 7451c309c7 clk: qcom: gdsc: Ensure regulator init state matches GDSC state 
[ Upstream commit 9711759a87a041705148161b937ec847048d882e ]

As GDSCs are registered and found to be already enabled gdsc_init()
ensures that 1) the kernel state matches the hardware state, and 2)
votable GDSCs are properly enabled from this master as well.

But as the (optional) supply regulator is enabled deep into
gdsc_toggle_logic(), which is only executed for votable GDSCs, the
kernel's state of the regulator might not match the hardware. The
regulator might be automatically turned off if no other users are
present or the next call to gdsc_disable() would cause an unbalanced
regulator_disable().

Given that the votable case deals with an already enabled GDSC, most of
gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just
clearing the SW_COLLAPSE_MASK and enabling hardware control to simply
call regulator_enable() in both cases.

The enablement of hardware control seems to be an independent property
from the GDSC being enabled, so this is moved outside that conditional
segment.

Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to
happen regardless of the initial state this is grouped together with the
other sc->pd updates at the end of the function.
