clk: qcom: clk-branch: Fix invert halt status bit check for votable clocks
BRANCH_HALT_ENABLE and BRANCH_HALT_ENABLE_VOTED flags are used to check
halt status of branch clocks, which have an inverted logic for the halt
bit in CBCR register. However, the current logic in the _check_halt()
method only compares the BRANCH_HALT_ENABLE flags, ignoring the votable
branch clocks.
Update the logic to correctly handle the invert logic for votable clocks
using the BRANCH_HALT_ENABLE_VOTED flags.
Fixes: 9092d1083a ("clk: qcom: branch: Extend the invert logic for branch2 clocks")
