Kernel - Completely remove DFLTPHYS

* There is no need to have two different macros define the maximum
allowed IO size for low-level operations; replace DFLTPHYS by
MAXPHYS in the entire kernel.

Kernel - Completely remove DFLTPHYS

* There is no need to have two different macros define the maximum
allowed IO size for low-level operations; replace DFLTPHYS by
MAXPHYS in the entire kernel.

* Old drivers typically used DFLTPHYS without a second thought,
assuming it would always be the same value; they may have hard
limitations and break if bigger I/O sizes are suddenly used.
Be sure to explicitely limit their maximum allowed I/O size to
64KB and keep them working.

* The command was not properly masking atadev->param.sectors_intr,
resulting in the setting of a value which some hard drives (OCZ SSD)

This mainly just gets rid of an error message on the console.
SET_MULTI is typically a NOP on most SATA drives.

M_NOWAIT can only be used in a driver where a failed memory allocation is
recoverable, such as in a network driver. FreeBSD seems to have a looser
definition but in DragonFly M_NOWAIT really means M_NOWAIT ... any blocking
at all, including waiting on the BGL or getting the kernel_map lock,
will result in a failure NULL.

Change all M_NOWAIT's to either M_WAITOK or M_INTWAIT.

Initial import of the port of the new(er) FreeBSD ATA code.

Note this code has not yet been hooked into the build as such, unless you (unwisely) specify the devices in your kernel config according to sys/conf/files. The modules are also excluded from the module build due to not having a SUBDIR entry in sys/dev/disk/Makefile. The PCI code isn't yet operation pending a patch for sys/bus/pci/pci.c I will send to kernel@ shortly. It short-circuits lazy resource allocation for PCI ATA controllers in legacy mode (i.e. on legacy ISA ATA addresses, which are not configured in the PCI BARs).

The userland utility used to control nata ('natacontrol') and documentation will follow later. Also, be aware only nata, natapci, natadisk and natapicd have seen testing on real hardware so far. nataraid, natausb and natacam are probably not compilable yet, I need to clean those up.
