brcmfmac: defer DPC processing during probe 

The sdio dpc starts processing when in SDIOD_STATE_DATA. This state was
entered right after firmware download. This patch moves that transition
just before enabling sdio interrupt handling thus avoiding watchdog
expiry which would put the bus to sleep while probing.
