This changes the reference voltage regulator matching string from "refin"
to "vref". This is to be consistent with other A/DC chips that also use
"vref-supply" in their device tree bindings.

This drops the "ti-" prefix from the module name. It makes the module name
consistent with other iio ti-ads* drivers and it makes the driver work
with device tree (the spi subsystem drops the "ti," prefix when matching
compatible strings from device tree).
Tested working on LEGO MINDSTORMS EV3 with the following device tree node:
adc@3 {
compatible = "ti,ads7957";
reg = <3>;
#io-channel-cells = <1>;
spi-max-frequency = <10000000>;
vref-supply = <&adc_ref>;
};

This adds a new driver for the TI ADS7950 family of ADC chips. These
communicate using SPI and come in 8/10/12-bit and 4/8/12/16 channel
varieties.
