Two gameport drivers need __devexit_p wrapped around their remove
functions.  A newer binutils caught this is a link error.  This patch fixes
that.

Wrapped a __devexit_p around the 'remove' functions of two gameport
drivers.  The lack of __devexit_p was wrong according to linux/init.h,
differed from the practices in nearby files, and caused a link error with
binutils 2.14.90.0.5.
