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.
