- In cfi_probe() iterate over all chip widths for every port width to find
x8/x16 configurations, or two x8 chips forming a x16 port width.
- The offset in cfi_cmd() is now always given for 64-bit port width.
It will be scaled down for the actual port width to avoid problems
with 0x2aa -> 0x554 instead of 0x555.
- Added missing cfi_reset_default() in cfi_jedec_id(). The reset is
needed, because the chip was still in CFI-Query mode.
- Removed everything dealing with cfi_opmodes. It only complicates things
and I found no reason for keeping them. The port width and chip width
is known, so I just introduced a new cfi_read_qry() function which reads
a single word using bus_space_read_N() from the QRY structure, which
can be checked for 'Q', 'R' and 'Y'. That's all we need, before
reading and unpacking the whole QRY and PRI structures.
- Added two new fields, cfi_unlock_addr1 and cfi_unlock_addr2 to
the cfi struct. The unlock offsets should be kept variable, depending
on the manufacturer or command set version.

Changes have been discussed with cliff@.

when unpacking CFI QRY data, byte order within a word is host order,
but order across words appears to be invariant across -el and -eb systems.

- add little endian variants of cfi_opmodes tables (untested)
- try to reduce glop factor in cfi_jedec_fill()

- dump raw QRY and/or JEDEC data depending on CFI_DEBUG_QRY, CFI_DEBUG_JEDEC
- add ability to emulate CFI based on table lookup keyed by JEDEC IDs.
- warn if CFI command set is unknown

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
