dgrs: remove from build, config, and maintainer list

Stop building and configuring driver for Digi RightSwitch, which was
never actually sold to anyone, and remove it from MAINTAINERS.

In response to an investigation into the firmware of the "Digi Rightswitch"
driver, Andres Salomon discovered:

Since the product never reached market, clearly nobody is using this orphaned
driver.
