wimax/iwmc3200: overwrite SDIO IOR timeout value to avoid platform hang
The default SDIO IOE wait timeout returned from iwmc3200-wimax's CCCR
is not efficient. This inefficiency will actually cause problems on
Moorestown platforms (system hang).
This is a sillicon bug that requires a software patch to by
overwritting func->enable_timeout. The new value I2400MS_IOR_TIMEOUT
is recommended and verified from the system integration results.
Future sillicon releases will have this default value corrected in the
future.
