[PATCH 2/2] arm64: dts: amlogic: s4: fix mmc clock assignment

[Jerome Brunet]

MMC A and C are mis-represented as having their "clkin0" input connected to
xtal while it is actually connected to the MMC clock, mostly in an attempt
to provide 24MHz to the device on this input.

Fix this and assign the clock to 24MHz to actually provide the required
rate.
