Add Amber as new machine (#1569)

* Add Amber machine Introduce a new machine for Amber. Store it under Raspberry Pi boards since Amber is based on the Raspberry Pi Compute Module 4. This way we can reuse existing scripts. * Add kernel patches for Amber Add kernel patches which add a custom device tree for Amber. * Add device wipe support via GPIO button Allow to wipe the device by pressing and holding the red button. * Enable serial console by default Enable serial console on the on-board USB-to-UART adapter as well as on the GPIO header. * Use 64-bit mode by default Support only 64-bit for Amber, it is mature enough.
