SPI: tle620x power switch driver
Add support for the Infineon TLE62x0 series of low-side driver chips, such as the TLE6220 or TLE6230. These can be viewed as output GPIOs specialized for power switching applications. The driver provides a userspace interface to those GPIOs, and to the switch status they provide.
