bnx2x: MSI support
Enabling MSI on top of MSI-X and INTA. Also changing the module parameter to
allow choosing INTA or MSI even when MSI-X is available. The default status
block should not be reversed for endianity. Since MSI can issue
re-configuration, the interrupt disable function now requires mmiowb
