cfi flash: Fix alignment problem ...

The intel cfi buffer write has a problem with writing when
the alignment of the buffer in memory is smaller than the
flash bus width.

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 aligned (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-aligned address with a 32 bit pointer.

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

net: dhcp: allow to set transmitted user class ...

For net boot setups it is useful to submit boot params like server or
bootfile over dhcp. To distinguish diffrent type of OS running on the same hardware,
a custom vendor id can be sent in dhcp discover/request messages.

E.g. the ISC dhcp server can be configured with

 | option client-uuid code 97 = { unsigned integer 8, string };
 | class "at91sam9x5ek" {
 |         match if substring (option vendor-class-identifier,0,20) = "barebox-at91sam9x5ek";
 |
 |         filename "/tftpboot/atmel/at91sam9x5/sam9x5ek/zImage";
