Subject: [PATCH 1/2] mfd: ab8500-debugfs: add function declaration

We get 1 warning when building kernel with W=1:
drivers/mfd/ab8500-debugfs.c:1587:28: warning: no previous prototype for 'suspend_test_wake_cause_interrupt_is_mine' [-Wmissing-prototypes]

In fact, this function need be declared in a header files.

So this patch adds function declaration in
include/linux/mfd/abx500/ab8500.h.
