[PATCH] platform/x86: intel_pmc_core: Avoid a u32 overflow

The register (SLP_S0_RES) at offset slp_s0_offset is a 32 bit register. The pmc_core_adjust_slp_s0_step() could overflow the u32 value while returning it after adjusting the step. Thus change to u64, this is already accounted for in debugfs attribute (that wants to output a 64 bit value). Signed-o
