[PATCH v3 7/8] dt-bindings: Add 1027/1029/1031 SPI ADCs as trivial devices

[Miquel Raynal]

In the same time, remove the dedicated bindings file which is now
useless.

-Required properties:
-  - compatible: Should be "maxim,max1027" or "maxim,max1029" or "maxim,max1031"
-  - reg: SPI chip select number for the device
-
-Optional properties:
-  - interrupts: IRQ line for the ADC
