Subject: [PATCH 0/4] Add CMN PLL clock controller support for IPQ5424

The CMN PLL block of IPQ5424 is almost same as that of IPQ9574
which is currently supported by the driver. The only difference
is that the fixed output clocks to NSS and PPE from CMN PLL have
a different clock rate. In IPQ5424, the output clocks are supplied
to NSS at 300 MHZ and to PPE at 375 MHZ.

Two related clock identifiers NSS_300MHZ_CLK and PPE_375MHZ_CLK
are added for IPQ5424. The new table of output clocks is added
for the CMN PLL of IPQ5424, which is acquired from the device
according to the compatible.
