Crust firmware for the PinePhone

Needs cleanup and doesn't build nicely, this can probably be entirely bypassed by just enableing or1k-elf in Alpine's gcc-cross-embedded and binutils-cross-embedded and using that compiler.

The crust package is also now build specifically for the PinePhone, this probably should be making some neat subpackages like it's done for u-boot.

Closes #550 (closed)

To test this MR, install the packages from this MR on your device, update u-boot with update-u-boot if you're not flashing a new image, and run echo mem > /sys/power/state.

@MartijnBraam: here is how I recommend to move this forward, so we get it in ASAP but also have a proper long-term plan for it: #550 (closed)

changed milestone to %[device] PinePhone support

added categorydevice ~8753996 labels

This is a high priority MR imo. Needed to get the phone viable as a daily driver in any shape or form.

Please update to the latest crust commit, this has support for modem wakeup

@MartijnBraam what's the progress on this?

I'm sure that we will resolve it within this month.

Help in resolving it faster is welcome, otherwise please be patient. Thumb down emojis are not helping

I'm going to see if I can add or1k support to gcc-cross-embedded in Alpine. It'll make this MR a whole lot smaller and easier.
