msm: clock-8960: Add support for measuring CPU and L2 clocks

Add measurement support for l2_m_clk, krait0_m_clk and
krait1_m_clk to debugfs, which can be used to route out these
clocks to the PLL test pin. Software measurement is also
supported, but its usefulness is limited due to dynamic gating
of these clocks during the measurements, and the fact that some
rates for these clocks may be higher than the maximum rate the
measurement hardware can resolve.
