[PATCH] chardev: GPIO for SCx200 & PC-8736x: use dev_dbg in common module
Use of dev_dbg() and friends is considered good practice. dev_dbg() needs a
struct device *devp, but nsc_gpio is only a helper module, so it doesnt
have/need its own. To provide devp to the user-modules (scx200 & pc8736x
_gpio), we add it to the vtable, and set it during init.
Also squeeze nsc_gpio_dump()'s format a little.

My BIOS does this, so I take minimum action here
