PM / OPP: Don't support OPP if it provides supported-hw but platform …
…does not The OPP framework allows each OPP to set a opp-supported-hw property which provides values that are matched against supported_hw values provided by the platform to limit support for certain OPPs on specific hardware. Currently, if the platform does not set supported_hw values, all OPPs are interpreted as supported, even if they have provided their own opp-supported-hw values. If an OPP has provided opp-supported-hw, it is indicating that there is some specific hardware configuration it is supported by. These constraints should be honored, and if no supported_hw has been provided by the platform, there is no way to determine if that OPP is actually supported, so it should be marked as not supported.
