The IMC free-running counters on Sapphire Rapids server are also accessed by MMIO, which is similar to the previous platforms, SNR and ICX. The only difference is the device ID of the device which contains BAR address. Factor out snr_uncore_mmio_map() which ioremap the MMIO space. It can be reused in the following patch for SPR. Use the snr_uncore_mmio_map() in the icx_uncore_imc_freerunning_init_box(). There is no box_ctl for the free-running counters.
