char: add missing NetWinder MODULE_DESCRIPTION() macros

Since commit 1fffe7a ("script: modpost: emit a warning when the
description is missing"), a module without a MODULE_DESCRIPTION() will
result in a warning with make W=1. The following warnings are being
observed in drivers/char when CONFIG_ARCH_NETWINDER is enabled:

WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/char/ds1620.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/char/nwbutton.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/char/nwflash.o

Add the missing invocations of the MODULE_DESCRIPTION() macro.
