This series add driver support for cpufreq Apple A7-A11, T2 SoCs.
Device Tree nodes will be included in another series.

Changes since v2:
- Use NSEC_PER_USEC instead of 1000 as multplier.

v2: https://lore.kernel.org/asahi/20241212070344.3858-1-towinchenmi@gmail.com/T

Changes since v1:
- transition_latency is in ns, APPLE_DVFS_TRANSITION_TIMEOUT in us.
Multiply APPLE_DVFS_TRANSITION_TIMEOUT by 1000 before setting it as
transition_latency.

v1: https://lore.kernel.org/asahi/20241211112244.18393-1-towinchenmi@gmail.com/T
