[PATCH] checkpatch: testing more config for Kconfig help text

[Yingjoe Chen]

Current help text check only check a config option if it is followed
by another config.
Adding check for help text if the next entry is menuconfig, choice/
endchoice, comment, menu/endmenu, if/endif, source or end of file.
