ARM: dts: STiH407-family: Provide interconnect clock for consumption in ST SDHCI
The STiH4{07,10} platform contains some interconnect clocks which are used by various IPs. If these clocks aren't handled correctly by ST's SDHCI driver MMC will break and the following output can be observed: [ 13.916949] mmc0: Timeout waiting for hardware interrupt.
