nor: don't use sector for ERASE_START ...

Similar to ac2d4d7, 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:

cfi_send_gen_cmd(0xAA, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL);

(Notice the third parameter which is simply chip->start).

Solves erase problems with SST flashes.

cfi_flash: fix alignment problem ...

This patch fixes a alignment problem which may show during this
scenario:
- 32 or 64 attached NOR flash
- flashing an image directly from network to the nor flash

The involved network driver is "smc9111.c".

The data that comes from the network stack and should be written into
the flash isn't 32 bit alligned (at least with this network driver).
This is probably due to the 48 bit wide ethernet addresses.

However the "cfi_flash.c" driver doesn't handle this situation, and
accesses the not-alligned address with a 32 bit pointer.

This patch fixes the problem by reducing the access width if an
alligment problem between source and destination is found.
