Subject: [PATCH v2 4/7] platform/x86: intel_pmc_core: Remove slp_s0 attributes from tgl_reg_map

If platforms such as Tiger Lake has sub-states of S0ix, then both
slp_s0_debug_status and slp_s0_dbg_latch entries become invalid. Thus,
remove slp_s0_offset and slp_s0_dbg_maps attributes from tgl_reg_map, so
that both the entries are not created.
