Effectively disabling the mode changing bits in the loader. No matter which
way we go with it, it seems to be wrong- either the firmware doesn't change
the resolution and reports the resolution we requested, or the firmware
changes the resolution and doesn't report the resolution we requested. It
some cases, it does the right thing, but the bad cases outweight those.
Interested individuals can still set efi_max_resolution to 1080p or whatnot
in loader.conf(5) to restore the new behavior, but the new behavior does not
work out well for many cases.
Discussed with: imp
Default the max resolution to 1080p, we'll accept Width x Height
specifications along with the following presets:
- 480p
- 720p
- 1080p
- 2160p or 4k
- 5k

The former is fairly vague; these are FDT overlays to be applied to the
running system, so /boot/dtb is a sensible location to put it without
cluttering up /boot/dtb even further if desired.
These tend to have less coverage in other places and they don't have
defaults as of yet, so mention them here:
- fdt_overlays
- kernels_autodetect (lualoader only)
Remove almost all of the _load=XXX options (kept only those relevant
to splash screens, since there were other settings).
Remove the excessively cutesy comment blocks.
Remove excessive comments and replace with similar content
Remove gratuitous blank lines (while leaving some)
We have too many modules to list them all here. There's no purpose in
doing so and it's a giant hassle to maintain. In addition the extra
~500 lines slow this down on small platforms. It slowed it down
so much small platforms forked, which caused other issues...
This is a compromise between those two extremes.
We really only need one loader.conf. The other loader.conf was created
because the current one took forever to parse in FORTH. That will be
fixed in the next commit.
