clk: qcom: mmcc-msm8974: remove ocmemcx_ahb_clk
According to a commit in the 3.4 vendor kernel sources[0] the
ocmemcx_ahb_clk clock "is controlled by RPM and should not be touched by
APPS.".
[0] https://git.codelinaro.org/clo/la/kernel/msm/-/commit/37df5f2d91b4d5768b37fcaacaeea958dd683ebc
And indeed, when using MDSS+GPU+OCMEM on MSM8226 and not using
clk_ignore_unused, when Linux tries to disable the clock the device
crashes and reboots.
And since there's also no evidence of this clock in msm8974 vendor
kernel sources, remove the clock for msm8226 and msm8974.
