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.

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

Use a header file hack to cope with Linux/NetBSD namespace clashes.

ALIGN

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.

Device hangs on pci disable in match; try skipping enable/disable.

Use the struct device pointer that works, not the nonexistent one.

Guess the right cpu_coherent setting.

Tag the pci_enable/disable_device calls that seem necessary.

Ifdef out pci_device_enable/disable that pmf handles for us.

Fix typos in pci bus dma tag acquisition.

Mark some NetBSDisms as such.

Don't pass zero to __ffs64 -- it finds zero indigestible.

Sprinkle static on local functions with no prior prototypes.

Kludge to pass bus_space_tag through nvif mappings.

- New `ioctl' NVIF_IOCTL_V0_MAP_NETBSD returns bus_space_tag_t too.
. Blocked from userland. (Would only disclose a kernel virtual
address, so not terribly serious.)
- struct nvif_driver::map function takes bus_sapce_tag, returns
bus_space_handle in addition to kva pointer.
- struct nvif_driver::unmap function takes bus_space_tag and
bus_space_handle rather than kva pointer.
- Teach various nvkm object types to return bus space tags too.
- Map them all with BUS_SPACE_MAP_LINEAR so the vaddr works.
