[PATCH 3/4] brcmfmac: postpone interrupt register function

["Franky Lin" <frankyl@broadcom.com>]

For out of band interrupt which is going to be introduced shortly,
the interrupt register function must be called after firmware is
downloaded. This patch moves it from brcmf_sdbrcm_probe to
brcmf_sdbrcm_bus_init.
