staging: gpib: gpio bitbang console messaging cleanup

Enable module name to be printed in pr_xxx and dev_xxx

Change pr_info in the dbg_printk macro to dev_dbg.

In order for dbg_printk macro to have the board variable
defined the signatures and calls to bb_buffer_print and
set_atn were changed to include board as a parameter.

Remove the #ifdef CONFIG_GPIB_DEBUG code.

Remove commented dbk_printk's.

Change dbg_printk(0, to dev_err where an error message is needed.

Remove dbg_printk for "not implemented" functions.

Remove "gpib_bitbang:" prefix in pr_err as it will be printed
with the module name.
