cpufreq: apple-soc: Switch to the lowest frequency on suspend
Without this, the CPUs are left in a random pstate. Since we don't
support deep idle yet (which powers down the CPUs), this results in
significantly increased idle power consumption in suspend.

Remove the first one, since this is not actually used.

cpufreq: apple-soc: Add new driver to control Apple SoC CPU P-states
This driver implements CPU frequency scaling for Apple Silicon SoCs,
including M1 (t8103), M1 Max/Pro/Ultra (t600x), and M2 (t8112).
Each CPU cluster has its own register set, and frequency management is
fully automated by the hardware; the driver only has to write one
register. There is boost frequency support, but the hardware will only
allow their use if only a subset of cores in a cluster are in
non-deep-idle. Since we don't support deep idle yet, these frequencies
are not achievable, but the driver supports them. They will remain
disabled in the device tree until deep idle is implemented, to avoid
confusing users.
This driver does not yet implement the memory controller performance
state tuning that usually accompanies higher CPU p-states. This will be
done in a future patch.
