[TG3]: Add basic register access function pointers

Browse source

This patch adds the basic function pointers to do register accesses in
the fast path. This was suggested by David Miller. The idea is that
various register access methods for different hardware errata can easily
be implemented with these function pointers and performance will not be
degraded on chips that use normal register access methods.

The various register read write macros (e.g. tw32, tr32, tw32_mailbox)
are redefined to call the function pointers.
