bnx2x: Add support for BCM57711 HW

Supporting the 57711 and 57711E - refers to in the code as E1H. The
57710 is referred to as E1.

To support the new members in the family, the bnx2x structure was
divided to 3 parts: common, port and function. These changes caused some
rearrangement in the bnx2x.h file.

A set of accessories macros were added to make access to the bnx2x
structure more readable
