[PATCH] chardev: GPIO for SCx200 & PC-8736x: put gpio_dump on a diet

Shrink scx200_gpio_dump() to a single printk with ternary ops.  The function
is still ifdef'd out, this is corrected in next patch, when it is actually
used.

The patch 'inadvertently' changed loglevel from DEBUG to INFO.  This is Good,
because in next patch, its wired to a 'command' which the user can invoke when
they want.  When they do so, its because they want INFO to support their
developement effort, and we want to give it to them without compiling a DEBUG
version of the driver.
