perf/x86/intel/uncore: Factor out common MMIO init and ops functions
Some uncore PMON registers are located in the MMIO space. For the client
machine, the MMIO space is usually located at D0:F0 but in a different
BAR. For example, some uncore PMON registers are located in the SAF BAR,
not the MCHBAR in the Lunar Lake.
The current __uncore_imc_init_box() hard code the BAR information.
Factor out the uncore_get_box_mmio_addr() which uses the BAR information
as a parameter.
The only change is the error output message. The hardcode name 'MCHBAR'
is replaced by the offset of a BAR.
Add a new macro, MMIO_UNCORE_COMMON_OPS(), since the MMIO ops functions
are usually the same among different generations.
