arm64: dts: samsung,coreprimevelte: add SDIO

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.
