From: Prasanna Kerekoppa <prasanna.kerekoppa@cypress.com>

Channel info passed by supplicant is not given to firmware. This causes
delay (about 3seconds) due to full scan. Supplicant already provides the
channel info for the specific SSID. channel_hint carries this channel
info for the connect call back.

Patch has been verified on 43012 and 43455.
