Jaswinder Singh 949b42544a 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).

# There are three cases to care about:
# 1. Building kernel with CONFIG_FIRMWARE_IN_KERNEL=y -- $(fw-shipped-y) should
# include the firmware files to include, according to .config
# 2. 'make modules_install', which will install firmware for modules, and
# _also_ for the in-kernel drivers when CONFIG_FIRMWARE_IN_KERNEL=n
# 3. 'make firmware_install', which installs all firmware, unconditionally.
# For the former two cases we want $(fw-shipped-y) and $(fw-shipped-m) to be
# accurate. In the latter case it doesn't matter -- it'll use $(fw-shipped-all).
# But be aware that the config file might not be included at all.
