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:

Uwe tested read, write, erase with this patch on a random board to make
sure nothing breaks.

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.

flasher infrastructure. 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.
Tested by Uwe on real hardware.
