6090885597 mfd: Fix return type of lm533 attribute is_visible
Since commit 587a1f1659 ("switch ->is_visible() to returning umode_t")
the return type of is_visible is umode_t rather than mode_t.

This silences a compiler warning on some architectures where these types
are not compatible.

168755ebb1 mfd: Silence an lm3533 gcc warning
This is supposed to be umode_t.  It causes a GCC warning:
drivers/mfd/lm3533-core.c:440:2: warning: initialization from incompatible pointer type [enabled by default]
drivers/mfd/lm3533-core.c:440:2: warning: (near initialization for ‘lm3533_attribute_group.is_visible’) [enabled by default]
