2015-01-21phy: miphy28lp: Pass sysconfig register offsets via syscfg dt property.Gabriel FERNANDEZ1-27/+16
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy28lp phy driver to access sysconfig register offsets via syscfg dt property. This is because the reg property should not be mixing address spaces like it does currently for miphy28lp. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. I have updated the miphy28lp phy driver same way as Peter's implementation.
