Add CPU OPP table for IPQ8062, IPQ8064 and IPQ8065 SoC.
Use opp-supported-hw binding to correctly enable and disable the
frequency as IPQ8062 supports up to 1.0Ghz, IPQ8064 supports up to
1.4GHz with 1.2GHz as an additional frequency and IPQ8065 supports
1.7GHZ but doesn't have 1.2GHZ frequency and has to be disabled.

We can just make use of opp-supported-hw and define opp-384...-0,
opp-384..-1 etc. with a valid corresponding bitmask in opp-supported-hw
otherwise it's somewhat confusing to follow, I think..
