So put them in the common file sbsa.json of arm64, so that other cores besides n2/v2 can also be reused. Slots may be different in each architecture, so added "#slots" literal to get different constant for each architecture. The value of slots comes from the register PMMIR_EL1, which I can read in /sys/bus/event_source/device/armv8_pmuv3_*/caps/slots. PMMIR_EL1.SLOT might read as zero if the STALL_SLOT event is not implemented or the PMU version is lower than ID_AA64DFR0_EL1_PMUVer_V3P4.
