staging: tidspbridge: fix an erroneous removal of parentheses

Commit 4a9fdbb (staging: core: tiomap3430.c Fix line over 80 characters.)
erroneously removed the parentheses around the function pointer leading
to the following build error (when enabling the build of TI DSP/Bridge
driver):

drivers/staging/tidspbridge/core/tiomap3430.c: In function 'bridge_brd_monitor':
drivers/staging/tidspbridge/core/tiomap3430.c:283:10: error: invalid type argument of unary '*' (have 'u32')
make[3]: *** [drivers/staging/tidspbridge/core/tiomap3430.o] Error 1

Fix this build error properly.

Fixes: 4a9fdbb (staging: core: tiomap3430.c Fix line over 80 characters.)
