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

[Viresh Kumar <viresh.kumar@linaro.org>]

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

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

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