b43: Add firmware markers support
This adds support for firmware markers. With firmware markers it's easily possible to check whether the firmware runs some codepath or not. The driver will throw a message when the firmware executes a MARKER(x). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
