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).
