Run fixups based on the JEDEC manufacturer ID independent of the
command set ID.
This changes current behaviour: Previously, geometry reversal for AMD
chips were done based on the command set ID, while they are now done
based on the JEDEC manufacturer and device ID.
Also add fixup for top-boot Atmel chips.

Move fixing up like geometry reversal into separate functions.
The geometry reversal fixup is now performed
by altering the qry structure directly, which makes the sector init
code slightly cleaner.

Introduce flash_read{8,16,32,64) and flash_write{8,16,32,64} and use
them to access the flash memory. This makes it clearer when the flash
is actually being accessed; merely dereferencing a volatile pointer
looks just like any other kind of access.

Similar to ac2d4d71ba, copy the behaviour
from Linux which does:
cfi_send_gen_cmd(0x80, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL);
Notice the third parameter which is simply chip->start. Needed for some
SST-flashes.

Copy the behaviour from Linux which does:

(Notice the third parameter which is simply chip->start).
Solves erase problems with SST flashes.

This file has no useful things for others than the driver,
so move it next to the driver and remove the corresponding
include from other files.
