In order not to affect other clocks, remove the apll from the
parent list of other clocks and only core, mac and lcdc can
select apll as parent.

Some clocks may get disabled as a side effect of another clock
being disabled, because have no consumers. Says the dclk_hdmi's parent may
change from apll to gpll, but the apll's son clocks are very less.

1. The first parent name of sclk_cif_out_src is wrong, it is
"sclk_cif_src".
2. The MUX configuration for sclk_cif_out_src is wrong, it should
be muxdiv_offset=29, mux_shift=2, mux_width=1.

This flag was in place to prevent important clocks from getting gated
while they had no users. Now that the driver supports clocks
properly, we can drop this.

While the CSV3 field of the ID_AA64_PFR0 CPU ID register can be checked
to see if a CPU is susceptible to Meltdown and therefore requires kpti
to be enabled, existing CPUs do not implement this field.
We therefore whitelist all unaffected Cortex-A CPUs that do not implement
the CSV3 field.
