In the Intel Wireless Multicomm 3200, the initialization is
orchestrated by a component called Top. This component also monitors
how many times a function is reset (via sdio_disable) to detect
possible issues and will reset the whole multifunction device if any
function triggers a maximum reset level.

During WiMAX's probe, the driver needs to wait for Top to come up
before it can enable the WiMAX function. If it cannot, it will return
-ENODEV and the Top driver will rescan the SDIO bus once done
loading.

Currently, the WiMAX SDIO probe routine was trying a few times before
returning -ENODEV, and this was triggering Top's too-many-resets
detector. This is, in any case, unnecessary because the Top driver will
force the bus rescan when the functions can be probed successfully.

Added then a maxtries argument to i2400ms_enable_func() and set it to
1 when calling from probe. We want to reuse this function instead of
flat calling out sdio_enable_func() to take advantage of hardware
quirk workarounds.
