[PATCH] chardev: GPIO for SCx200 & PC-8736x: add platform_device for use w dev_dbg

Adds platform-device to (just introduced) driver, and uses it to replace many
printks with dev_dbg() etc.  This could trivially be merged into previous
patch, but this way matches better with the corresponding patch that does the
same change to scx200_gpio.
