John Ericson 8929989614 lib: Clean up how linux and gcc config is specified
The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.

This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.

`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.

The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.

Richard Marko 6c9df40a4b nixos/device-tree: improve overlays support
Now allows applying external overlays either in form of
.dts file, literal dts context added to store or precompiled .dtbo.

If overlays are defined, kernel device-trees are compiled with '-@'
so the .dtb files contain symbols which we can reference in our
overlays.

Since `fdtoverlay` doesn't respect `/ compatible` by itself
we query compatible strings of both `dtb` and `dtbo(verlay)`
and apply only if latter is substring of the former.

Also adds support for filtering .dtb files (as there are now nearly 1k
dtbs).

Florian Klink 387f3b58d2 hardware.deviceTree: add name
This can be used to explicitly specify a specific dtb file, relative to
the dtb base.

Update the generic-extlinux-compatible module to make use of this option.

Florian Klink 43424688db nixos/deviceTree: fix description
hardware.deviceTree.base points to a path, not a package (and also if of
types.path)

It defaults to ${config.boot.kernelPackages.kernel}/dtbs.

Gaelan 4ed7e23636 nixos/device-tree: fix package name in examples
deviceTree_rpi got renamed to device-tree_rpi a while back, so this updates the examples to reflect that.

Kai Wohlfahrt 28cf80acf8 nixos/hardware.deviceTree: Move things around
In response to comments, create a sub-folder for deviceTree packages
(starting with rpi), and a top-level package for helpers.

Kai Wohlfahrt dd0a951279 nixos/hardware.deviceTree: new module
Add support for custom device-tree files, and applying overlays to them.
This is useful for supporting non-discoverable hardware, such as sensors
attached to GPIO pins on a Raspberry Pi.
