gpio: brcmstb: Make really use of the new lockdep class

KAGA-KOKO · KAGA-KOKO · commit 8880c13734af · 2017-12-29T16:37:09.000+01:00
The recent extension of irq_set_lockdep_class() with a second argument added the new lockdep class to the mrcmstb driver, but used the already existing lockdep class as second argument, which leaves the new lockdep class defined but unused. Use the new lockdep class as that's what the change intended to do.
