471e2875f8 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] 37df5f2d91

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.

f7b7d30158 clk: qcom: clk-rcg2: Fix clock rate overflow for high parent frequencies 
If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.

Add PLL configuration for MSM8976 SoC, this SoC offers 3 HFPLL.
Small cluster offers two presets for 652-902Mhz range and 902Mhz-1.47Ghz.
For simplicity only add second range as smaller frequencies can be obtained
via apcs divider or safe parent this also saves us
a hassle of reconfiguring VCO bit and config_val.
A72 and CCI cluster only use single frequency range with their
outputs/post_dividers/vco_bits being static.
