The tle62x0 driver was ignoring all read errors. This patch makes it
pass such errors up the stack, instead of returning bogus data.

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.
