This modifies the bootrom initialization code of the i2400m driver so it can more easily support upcoming hardware. Currently, the code detects two types of barkers (magic numbers) sent by the device to indicate the types of firmware it would take (signed vs non-signed). This schema is extended so that multiple reboot barkers are recognized; upcoming hw will expose more types barkers which will have to match a header in the firmware image before we can load it. For that, a barker database is introduced; the first time the device sends a barker, it is matched in the database. That gives the driver the information needed to decide how to upload the firmware and which types of firmware to use. The database can be populated from module parameters. The execution flow is not altered; a new function (i2400m_is_boot_barker) is introduced to determine in the RX path if the device has sent a boot barker. This function is becoming heavier, so it is put away from the hot reception path [this is why there is some reorganization in sdio-rx.c:i2400ms_rx and usb-notifc.c:i2400mu_notification_grok()]. The documentation on the process has also been updated. All these modifications are heavily based on previous work by Dirk Brandewie <dirk.brandewie@intel.com>.
