[PATCH] chardev: GPIO for SCx200 & PC-8736x: add 'v' command to device-file
Add a new driver command: 'v' which calls gpio_dump() on the pin. The output
goes to the log, like all other INFO messages in the original driver. Giving
the user control over the feedback they 'need' is construed to be a
user-friendly feature, and allows us (later) to dial down many INFO messages
to DEBUG log-level.
