Add linux device tree entry related to the Minerva Chassis Management
Controller (CMC) specific devices connected to the Aspeed SoC (AST2600).
Changes from v1:
- Change adc0 and adc1 "ref_voltage" property to
"aspeed,int-vref-microvolt" which is defined in the binding file, and
choose the ADC internal reference voltage to 2500000 microvolts.

There was one warning when building. Please double check your code
compiles cleanly before submitting:
arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-minerva-cmc.dts:91.24-94.4:
Warning (i2c_bus_reg):
/ahb/apb/bus@1e78a000/i2c-bus@100/temperature-sensor@4B: I2C bus unit
address format error, expected "4b"
I've fixed that and added your patch to the aspeed tree for 6.7.
