firmware: convert acenic driver to request_firmware()
We store the firmware in its native big-endian form now, so the loop in
ace_copy() is modified to use be32_to_cpup() when writing it out.
We can forget the BSS,SBSS sections of the firmware, since we were
clearing all the device's RAM anyway. And the text,rodata,data sections
can all be loaded as a single chunk since they're contiguous (give or
take a few dozen bytes in between).

vicam: use request_firmware()
Although it wasn't actually using ihex records before, we use the Intel
HEX record format for this firmware -- because that gives us a simple
way to split it into separate chunks internally as we need, without
loading each part as a separate file.

firmware: convert Ambassador ATM driver to request_firmware()
Since it had various regions to be loaded to separate addresses, and it
wanted to do them in fairly small chunks anyway, switch it to use the
new ihex code. Encode the start address in the first record.
