[PATCH V2] PM / OPP: Use - instead of @ for DT entries

[Tony Lindgren]

> 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.
