[PATCH 3/5] bfa: rename some global variables

[Arnd Bergmann]

The global "supported_fc4s" and "max_xfer_size" variables have rather
generic names that might conflict with the same identifiers used in
other drivers, and we cannot make them 'static' because they are both
used across multiple files.

This adds a 'bfa_' prefix to ensure the identifiers are globally unique.
