clk: qcom: mmcc-msm8998: Add hardware clockgating registers to some clks
Hardware clock gating is supported on some of the clocks declared in there: ignoring that it does exist may lead to unstabilities on some firmwares. Add the HWCG registers where applicable to stop potential crashes. This was verified on a smartphone shipped with a recent MSM8998 firmware, which will experience random crashes without this change.
