Set some basic properties of the SDIO card of the samsung,coreprimevelte smartphone.
The SDIO is used as an interface for WiFi, Bluetooth and FM radio serviced by the Marvell 88W8777 (SD8777) chipset. Support for this chipset is currently not in-tree because the firmware is not available in linux-firmware, however it is possible to trivially run it out-of-tree using the mwifiex and Marvell Bluetooth drivers with some caveats.
