A new MMIO type uncore box is introduced on Snow Ridge server. The counters of MMIO type uncore box can only be accessed by MMIO. Add a new uncore type, uncore_mmio_uncores, for MMIO type uncore blocks. Support MMIO type uncore blocks in CPU hot plug. The MMIO space has to be map/unmap for the first/last CPU. The context also need to be migrated if the bind CPU changes. Add mmio_init() to init and register PMUs for MMIO type uncore blocks. Add a helper to calculate the box_ctl address. The helpers which calculate ctl/ctr can be shared with PCI type uncore blocks.
