4135f5cf7d Make ata_getrev() an optional method by implementing ata_null_getrev(). 
This fixes a bogus '???' boot message on Cambria boards with a CompactFlash
card.

066f913a94 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.

9f82379c24 Add experimental support for SATA Port Multipliers 
Support is working on the Silicon Image SiI3124/3132.
Support is working on some AHCI chips but far from all.

Remember this is WIP, so test reports and (constructive) suggestions are welcome!

0068f98f88 Take newbusification one step further, ie use the device_t more consequently 
all way through the code down the layers, instead of the mix'n'match that
resulted from the conversion done earlier.

ca8c70e9e3 Provide a default setmode method. 
This shaves off multiple copies of the same setmode stub.

5a5b148dd8 Change the ata_* methods to use a channel device instead of a 
controller device. This helps when there is no controller parent
to a channel (PPC port).
