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.
