clk: msm: clock: Include logic to treat votable clocks/GDSCs differently

On MSMCOBALT, the votable GDSCs might take longer to enable/disable
depending on a number of factors including if another entity outside
of HLOS tried disabling the GDSC at the same time that HLOS tried to
enable it. Add a higher polling timeout to accommodate this.
In addition, add flags to branch clocks which might be controlled via
the voting registers so that the driver does not print out a warning
if these clocks do not turn off even after removing the SW vote.
