Subject: [PATCH] Input: add missing MODULE_DESCRIPTION() macros

On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/input/touchscreen/cyttsp_i2c_common.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/input/misc/soc_button_array.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/input/matrix-keymap.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/input/vivaldi-fmap.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/input/tests/input_test.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes drivers/input/misc/sgi_btns.c which, although it did not
produce a warning with the x86 allmodconfig configuration, may cause
this warning with other configurations when either CONFIG_SGI_IP22 or
CONFIG_SGI_IP32 is enabled.
