[PATCH 2/2] arm: apple: Add initial Apple M2 support

[Janne Grunau]

Apple's M2 SoC very similar to the M1 and can use the same memory map.
The keyboard/trackpad on the MacBook Pro (13-inch, M2, 2022) uses
"dockchannel" as transport instead of SPI and needs a new driver.
USB, NVMe, uart, framebuffer and watchdog are working with the existing
drivers.
