RAPL MSR interface supports 2 power limits for package domain, and 1 power limit for other domains, while RAPL MMIO interface supports 2 power limits for both package and dram domains. And when 2 power limits are supported, the FW_LOCK bit is in bit 63 of the register, instead of bit 31. Remove the assumption that only pakcage domain supports 2 power limits. And allow the RAPL interface driver to specify the number of power limits supported, for every single RAPL domain it owns..
