[MFD] Fix gcc4 build errors in ucb1x00-core.c
drivers/mfd/ucb1x00-core.c:555: error: static declaration of 'ucb1x00_class' follows non-static declaration drivers/mfd/ucb1x00.h:109: error: previous declaration of 'ucb1x00_class' was here Since ucb1x00_class isn't used by anything, remove the extern declaration and the symbol export.
