arm64: dts: broadcom: bcm2712: Add second SDHCI controller node
Add SDIO2 node. On RPi5 it is connected to WiFi chip.
Add related pin, gpio and regulator definitions and
add WiFi node. With this and firmware already provided by
distributions, at least on openSUSE Tumbleweed, this is
sufficient to make WiFi operational on RPi5 \o/.
