Subject: [PATCH V5 3/8] clk: qcom: gcc-qdu1000: Fix clkref clocks handling

Update the GCC clkref clock's halt_check to BRANCH_HALT, as it's
status bit is not inverted in the latest hardware version of QDU1000
and QRU1000 SoCs. While at it, fix the gcc clkref clock ops as well.

Fixes: 1c9efb0bc040 ("clk: qcom: Add QDU1000 and QRU1000 GCC support")
