powerpc: Add support for multiple gfar mdio interfaces
The old code assumed there was only one, but the 8572 actually has 3. Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was preventing the multiple buses from having different ids. So we only keep the low 20 bits, which have the interesting info, anyway. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
