ARM: kirkwood: NETGEAR ReadyNAS Duo v2 .dts cleanup

The patch does some cleanup work on NETGEAR ReadyNAS Duo v2 .dts
file. Changes are listed below:

 - Converted from value to macros for GPIO voltage level
 - Converted all numeric input key values to macros
 - Made button names more explicit
 - Document ethernet PHY (Marvell 88E1318) via a comment
 - Added header for the file to describe content and author
 - Made G762 clock node name unique by including g762 in it
 - Fixed all node names and labels to use respectively '-' and '_'
 - Changed order of included files from general to local
 - Removed useless clocks and gpio-keys properties
