drm: Set CONFIG_ACPI in linux/acpi.h and make it build.

Leave a little ACPI-related functionality disabled for now, like
getting EDID out of ACPI -- needs a bit more work to make this work,
and I don't have hardware to work on that.

Should help with failures of the forms:

- unable to locate a BIOS ROM
- bios: unable to locate usable image

on various machines.

Match Linux's criterion for byte-swapping on big-endian CPUs.

Merge linux-drm-v5-6-rc3

Match Linux's criterion for byte-swapping on big-endian CPUs.

branches: 1.9.4;
Use a header file hack to cope with Linux/NetBSD namespace clashes.

Currently serves for:

ALIGN
mutex_init
mutex_destroy

branches: 1.8.2; 1.8.6; 1.8.10;
Be consistent about I/O byte ordering.

Leave XXX comments where it's not clear what we should do.

Allow nvkm_client_map to map subregions.

Linux ioremap does not care about overlapping mapped regions, but
bus_space_map does. Since nouveau ioremaps the entire register space
of BAR 0, and separately some subregions of it, we need to convey the
bus addresses in question to it in order to bus_space_subregion.

Kinda kludgey, but we don't care about running this in userland or
anything.

While here: initialize object->map.tag. Not physically necessary on
x86 as long as the x86_io_mem_tag is nonull, so this won't fix any
symptoms on x86, but it is wrong to leave it null.

Rename nouveau_devices_init/fini -> nvkm_devices_init/fini.

Matches newer upstream naming conventions better.

Fix typos. Use BUS_SPACE_MAP_LINEAR for vaddr later.

Fix 64-bit printfs.

Fix up some linux mutex init/destroy.
