iio: adc: add driver for MCP3204/08 12-bit ADC
This adds support for Microchip's 12 bit AD converters MCP3204 and
MCP3208. These chips communicates over SPI and supports single-ended
and pseudo-differential configurations.

Each of them just do a usb_control_msg() to the device and output
an error message if it fails. A similar message is also output by
firmware_upload() so the extra messages are redundant.
