Iyappan Subramanian 09c9e0593d dtb: xgene: fix: Backward compatibility with older firmware 
The following kernel crash was reported when using older firmware (<= 1.13.28).

The issue was that the older firmware does not support 10GbE and
SGMII based 1GBE interfaces.

This patch changes the address length of the reg property of sgmii0 and xgmii
nodes and serves as preparatory patch for the fix.
