[U-Boot] [PATCH 3/4] dm: gpio: Correct use of -ENODEV in drivers

[sjg at google.com]

In U-Boot -ENODEV means that there is no device. When there is a problem
with the device, drivers should return an error like -ENXIO or -EREMOTEIO.
When the device tree properties cannot be read correct , they should
return -EINVAL.

Update various GPIO drivers to follow this rule, to help with consistency
for future driver writers.
