staging: dgnc: Remove non-standard APR/RAPR printing macros

This patch removes non-standard macros used by dgnc driver for printing error
or debugging messages. These are replaced by dev_err/dev_dbg (when possible)
or pr_err. There were cases where the message is completely removed since is
not adding any useful information.
