add (experimental) pinephone/pda target

this requires cross compilation (particularly of the kernel), which is a bit too slow on this machine
to test since it uses qemu.

i can maybe switch to an older nixpkgs for the pda build which has the
kernel cached... or migrate my desktop to nixos and build the pinephone
image there :-)
