[PATCH V4 5/7] ARM: sun8i: Use - instead of @ for DT OPP entries

[Viresh Kumar]

Compiling the DT file with W=1, DTC warns like follows:

Warning (unit_address_vs_reg): Node /opp_table0/opp at 1000000000 has a
unit name, but no reg property

Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.
