perf/x86/intel/uncore: Support MMIO type uncore blocks

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.
