brcm80211: fmac: postpone dongle RF enabling.
BRCMF_C_UP is the command that asks the firmware to enable RF of dongle. Some firmware initialization steps must be performed during RF is down. Postpone BRCMF_C_UP firing until brcmf_netdev_open get called to ensure firmware have enough time to finish initialization.
