Subject: [PATCH 0/2] arm64: dts: amlogic: s4: mmc clock fixups

The patchset aims to address the issue raised here [1] for MMC B.

While checking this, I've found that MMC A and C also appear to be
improperly described in this platform's DT. The 2nd change fixes that.

I do not have an s4 platform available with me, so these changes have only
been compile tested but assigning the clock was actually tested on sm1.

To be on the safe side, the MMC clock should also be assigned on the other
SoCs. More changes will follow once things are sorted out for s4.
