bnx2: Use request_firmware()
Based on original patch by Ben Hutchings <ben@decadent.org.uk> and
Bastian Blank <waldi@debian.org>, with the following main changes:
Separated the mips firmware and rv2p firmware into different files
to make it easier to update them separately.
Added some code to fixup the rv2p code with run-time information
such as PAGE_SIZE.
Update version to 2.0.0.
