[PATCH 1/3] dgnc: Remove unneeded dgnc_state array of strings

[Giedrius Statkevičius]

Dgnc_state array of strings is never used anywhere and it seems pretty
useless anyway since the board state enum names speak for themselves.

[PATCH 2/3] dgnc: remove DGNC_VERIFY_BOARD macro

[Giedrius Statkevičius]

In sysfs methods struct device is guaranteed to not be NULL thus bd will
not be NULL in any way. Also, checking for bd->magic != DGNC_BOARD_MAGIC
and bd->state != BOARD_READY is redundant because we already don't
initialize broken boards since "dgnc: Don't save boards in memory that
have failed to initialize" and make sysfs files after initializing the
board in dgnc_driver.c or IOW they are already set for successfully
initialized boards before their sysfs files created (412 and 593 lines
in dgnc_driver.c).

[PATCH 3/3] dgnc: clean up comments at start of files

[Giedrius Statkevičius]

Remove FSF address because it's known in the past that it has changed.
Also, remove the pointless "do not change the coding style" comments
because it's one of the reasons why it's in staging and it's quite
contradictory to what it says in TODO. Also, they contain wrong e-mails
of people which are responsible for these drivers - see TODO or
MAINTAINERS for that. We can preserve the original copyright at the top
of the most files because it shows who originally made them.
