[PATCH 00/13] drivers/perf: apple_m1: Add M3/M4/A18 Pro Support

[Myria Sarvay via B4 Relay]

This series adds support for the CPU PMU in the new M3, M4 and A18 SoCs
presed in apple devices. These PMUs have new encodings for events, along
with larger codes for these events. All of these events are as Apple
describes them in the various kpep files found under /usr/share/kpep on
macOS 27. More events may exist, but we have no idea of their affinity,
or what they actually count, so we don't include them here.

These patches have been tested on my own M2 (t8133-j413) and M3
(t6031-j514c) devices, as well as by Yuvan on their M4 (t8132-j713)
device.

If possible, the device tree changes should probably go through
apple-soc, as this is where the recently picked up M4 Pro/Max dts are.
