[PATCH] powerpc/83xx: update kmeter1 defconfig and dts

[Holger Brunck <holger.brunck@ch.abb.com>]

From: Matteo Ghidoni <matteo.ghidoni@ch.abb.com>

The defconfig is synchronized and the missing
MTD_PHYSMAP, DEVTMPFS and I2C MUX support are switched on.

Additionally the I2C mux device is added to the DTS with
its attached temperature sensors and I2C clock frequency
is lowered.
