tg3: fix MMIO for PPC 44x platforms 

The driver stores the PCI resource addresses into 'unsigned long' variable
before calling ioremap_nocache() on them. This warrants kernel oops when the
registers are accessed on PPC 44x platforms which (being 32-bit) have PCI
memory space mapped beyond 4 GB.

The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion that
the PCI memory resource is mapped below 4 GB, but arch/powerpc/ code got rid
of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

[ Bump driver version and release date -DaveM ]
