- With the demise of !ATA_CAM, ATA_STATIC_ID is the only ata(4) related
option left but actually consumed by ada(4), so move it to opt_ada.h
and get rid of opt_ata.h.
- Fix stand-alone build of atacore(4) by adding opt_cam.h.
- Use __FBSDID.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.

Unbreak build.

Pointy hat to: me

MFp4:
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this options deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.

As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.atapi_dma tunable work again.

Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

Move from using devclass_find_free_unit(ata_devclass, 0) to -1 for the
unit number. Basically they are the same...

ata_generic_hw takes a dev as a parameter, not a channel.

Unbreak the powerpc build by fixing some ATA constants that were renamed.

Introduce channel-level setmode newbus method.

Thanks to sos for the code re-org that allowed this.
