This patch adds dummy gameport_register_port, gameport_unregister_port
and gameport_set_phys functions to gameport.h for the case when a driver
can't use gameport.

This fixes the compilation of some OSS drivers with GAMEPORT=n without
the need to #if inside every single driver.

This patch also removes the non-working and now obsolete SOUND_GAMEPORT.

This patch is also an alternative solution for ALSA drivers with similar
problems (but #if's inside the drivers might have the advantage of
saving some more bytes of gameport is not available).

The only user-visible change is that for GAMEPORT=m the affected OSS
drivers are now allowed to be built statically (but they won't have
gameport support).

# Yes, SOUND_GAMEPORT looks a bit odd. Yes, it ends up being turned on
# in every .config. Please don't touch it. It is here to handle an
# unusual dependency between GAMEPORT and sound drivers.
#
# Some sound drivers call gameport functions. If GAMEPORT is
# not selected, empty stubs are provided for the functions and all is
# well.
# If GAMEPORT is built in, everything is fine.
# If GAMEPORT is a module, however, it would need to be loaded for the
# sound driver to be able to link properly. Therefore, the sound
# driver must be a module as well in that case. Since there's no way
# to express that directly in Kconfig, we use SOUND_GAMEPORT to
# express it. SOUND_GAMEPORT boils down to "if GAMEPORT is 'm',
# anything that depends on SOUND_GAMEPORT must be 'm' as well. if
# GAMEPORT is 'y' or 'n', it can be anything".
