qcom: clock-cpu-8994: Set the safe rate to 199.2MHz

To prevent reconfiguration of the rate settable PLL when a
rate of 199.2MHz is requested, the rate of the safe parent
of each of the CPU muxes was set to 200MHz and cpufreq and
other drivers were made to request 200MHz. However, this is
causing confusion with setting up tables in other cpu frequency
dependent devices such as devfreq. Furthermore, since the
divider on the PLL main output of the rate-settable PLL is set
to 2, it will not be able to generate the 199.2MHz rate. Therefore,
set the safe rate to 199.2 MHz and eliminate the possibility of
confusion entirely.
