wimax/iwmc3200: increase wait time before enable retry

When trying to enable the iwmc3200 WiMAX SDIO function, we loop
waiting for the top controller to be up and running (at which point we
can succesfully enable the function). Between each try we wait for
I2400MS_INIT_SLEEP_INTERVAL ms.

Integration tests have found the current value of 10ms to be too
short; it was upped to 100ms to give more time to the top controller
to be ready.
