PM / OPP: Use - instead of @ for DT entries

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.

This is an very old issue:
https://www.spinics.net/lists/devicetree/msg120914.html
(reported year ago, please update the Reported-by)
and guide was to either use oppN format or whitelist opp nodes in dtc.
Apparently the second never happened...

Best regards,
Krzysztof

Given that this had already been reported one year before,
the reported-by credit should be given to Krzysztof.

Please drop my Reported-by.

I don't think we need to drop any of you. We can very well keep both

Yes, keeping both make most sense, I think.

Anyway, I found now the original report thread of Masahiro and I see
Mark's response about using '-'. In that case I am fine with this. I
would prefer to take only the exynos part (separated to ARMv7 and
ARMv8) through my tree but I already sent a pull request so I am fine
with this going directly to arm-soc.

I think you need to update also:
Documentation/devicetree/bindings/cpufreq/ti-cpufreq.txt
With that change:

This may end up going via the PM tree.

Oops. I searched for opp@ and missed the complex ones. There are some
DT files as well for TI which I missed. Will send a V2 with all that
fixed.
