clk: qcom: mmcc-msm8998: Don't check halt bit on some branch clks
[ Upstream commit 9906c4140897bbdbff7bb71c6ae67903cb9954ce ]
Some branch clocks are governed externally and we're only supposed to
send a request concerning their shutdown, not actually ensure it happens.
Use the BRANCH_HALT_SKIP define to skip checking the halt bit.
