clk: qcom: hfpll: Add MSM8976 PLL data

Browse Source 
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.
