Also:

* Remove the FDC_ATTACHED flag. It was supposed to prevent multiple
unloads but this is not necessary.

Remove fdc_alloc_resources, which should have happened in last commit.

Set fdc_dev in attach

Don't depend on implicit include of machine/bus.h in sys/rman.h, but instead
explicitly include it.

Update in preparation for adding the ACPI attachment.
* Add an fdtype ivar. This will be the equivalent of fd->type.
* Move enabling the FIFO to the end of attach.
* Unify reset code into fdc_initial_reset().
* Add fdc_write_ivar().
* Update isa and pccard attachments accordingly.
* Set the flags unconditionally in probe since they may be overridden by
other probe routines. Both before and now, we're depending on probe
being called a final time on the winning driver so the flags we get are
the ones we intended.
* Use the bus accessor macros instead of defining our own.
* Remove duplicate assigns of fd->type.

Break out the isa and pccard front ends from fdc. This is the first
step in making this driver more attachment neutral. Others plan on
adding acpi front ends.

Still need to cleanup the MI part of the driver because it isn't as
bus independent as it could be.

Mark our interrupt shareable and don't insist on DMA. This gets us closer
to working with a secondary floppy controller on a PC.

Bump __FreeBSD_version accordingly.

Update to reflect new location in the tree. This has been repo copied

different busses.

Fixed breakage of the formatting operation in rev.1.266. The wrong
clause of an if-else statement was removed.

Workaround some ACPI BIOSen which break the IO port into multiple
resources. (Note that the correct range is 0x3f7,0x3f0-0x3f5.) Such
devices will be detected as follows:

fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> port
0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0

To do this, we find the minimum and maximum start addresses for the
resources and use them as the base for the IO and control ports.
