Add LOW_SPAN_ACTIVE_DWELL_TIME and LOW_SPAN_PASSIVE_DWELL_TIME macro support to keep all 2.4g/5g active/passive dwell time same for low span scan mode. Disable adaptive dwell to firmware so that firmware cannot modify dwell time. Change-Id: Iff05dd7b37a40226c61b28a1e59ea8aa8c57cb52 CRs-Fixed: 3076163
