Subject: [PATCH v3 1/4] dt-bindings: opp: adreno: Update regex of OPP entry

In some cases, an OPP may have multiple varients to describe the
differences in the resources between SKUs. As an example, we may
want to vote different peak bandwidths in different SKUs for the
same frequency and the OPP node names can have an additional
integer suffix to denote this difference like below:

 opp-666000000-0 {
         opp-hz = /bits/ 64 <666000000>;
         opp-level = <RPMH_REGULATOR_LEVEL_SVS_L1>;
         opp-peak-kBps = <8171875>;
         qcom,opp-acd-level = <0xa82d5ffd>;
         opp-supported-hw = <0xf>;
 };

 /* Only applicable for SKUs which has 666Mhz as Fmax */
 opp-666000000-1 {
         opp-hz = /bits/ 64 <666000000>;
         opp-level = <RPMH_REGULATOR_LEVEL_SVS_L1>;
         opp-peak-kBps = <16500000>;
         qcom,opp-acd-level = <0xa82d5ffd>;
         opp-supported-hw = <0x10>;
 };

Update the regex to allow this usecase.
