msm: acpuclock-8974: Consolidate CPU and L2 HFPLL data

The HFPLL data for the CPU PLLs and the L2 PLL are the same with the
exception of the voltage data specified. The voltage data, however,
is only relevant for the L2 PLLs (since the CPU HFPLL voltage
requirements are captured as part of the CPU frequency/voltage table).
Because of this the tables can be combined.
