driver: Add OCE scan parameters

Add a flag to scan parameters that enables OCE scan features. If this
flag is set the device should enable the following features as defined
in the Optimized Connectivity Experience Technical Specification v1.0:
- Overwrite FILS request Max Channel Time with actual value (clause 3.8)
- Send Probe Request frame in high rate (at least 5.5 Mbps) (clause 3.12)
- Probe Request frame Transmission Deferral and Suppression (clause 3.5)
- Accept broadcast Probe Response frame (clause 3.6)
