Subject: [PATCH 1/5] bnx2x: Drop redundant callback function casts
NULL is already "void *" so it will auto-cast in assignments and
initializers. Additionally, all the callbacks for .link_reset,
.config_loopback, .set_link_led, and .phy_specific_func are already
correct. No casting is needed for these, so remove them.
