Even a failing chipset init (maybe due to unknown chipset) could still
get us reasonable probe results or at least forced reads.

FT2232 and IT87 programmers used functions of the dummy programmer
instead of fallback functions.
The dummy programmer is a "real" programmer with possible side effects
and its functions should not be abused by other programmers. Make
FT2232 and IT87 use official fallback functions instead. Create
fallback_shutdown(). Create fallback_chip_writeb(). Convert the
programmer #defines to an enum.

Add chip_{read,write}n to the external flasher infrastructure which
read/write n bytes at once.
Fix a few places where the code used memcpy/memcmp although that is
strictly impossible with external flashers.
Place a FIXME in the layout.c code because usage is not totally clear
and needs to be fixed to support external flashers.
As a nice side benefit, we get a noticeable speedup for builtin flash
reading which is now a memcpy() of the full flash area instead of a
series of single-byte reads.

Some MMIO accesses used volatile, others didn't (and risked
non-execution of side effects) and even with volatile, some accesses
looked dubious.
Since the MMIO accessor functions and the onboard flash accessor
functions are functionally identical (but have different signatures),
make the flash accessors wrappers for the MMIO accessors.
For some of the conversions, I used Coccinelle. Semantic patch follows:
@@ typedef uint8_t; expression a; volatile uint8_t *b; @@ - b[a] + *(b
+ a) @@ expression a; volatile uint8_t *b; @@ - *(b) |= (a); + *(b) =
*(b) | (a); @@ expression a; volatile uint8_t *b; @@ - *(b) = (a); +
mmio_writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + mmio_readb(b) @@
type T; T b; @@ ( mmio_readb | mmio_writeb ) (..., - (T) - (b) + b )

Use chipaddr instead of volatile uint8_t * because when we access chips
in external flashers, they are not accessed via pointers at all.
Benefits: This allows us to differentiate between volatile machine
memory accesses and flash chip accesses. It also enforces usage
of chip_{read,write}[bwl] to access flash chips, so nobody will
unintentionally use pointers to access chips anymore. Some unneeded
casts are removed as well. Grepping for chip operations and machine
memory operations doesn't yield any false positives anymore.
Compile tested on 32 bit and 64 bit Linux.

The emulation works by splitting 32 bit accesses into 16 bit accesses
and 16 bit accesses into to 8 bit accesses. That way, external flashers
can mix and match the amount of emulation they need.

- Read/write accesses through function pointers
- Command line parameter for internal/external flasher
- Board and chipset setup moved to internal init function
- Shutdown stuff moved to internal shutdown function
As a side benefit, this will allow us to undo chipset write enable
during shutdown.
