pinctrl: nomadik: shut up a warning for flags
The irq flags variable gets a warning like this after
commit bf4dae5ce1b95a5932e43036edcf3f1b324758c6
"pinctrl: nomadik: delete ancient pin control API":

drivers/pinctrl/pinctrl-nomadik.c: In function 'nmk_pmx_enable':
include/linux/spinlock.h:348:122: warning:
'flags' may be used uninitialized in this function
[-Wmaybe-uninitialized]
raw_spin_unlock_irqrestore(&lock->rlock, flags);
^
drivers/pinctrl/pinctrl-nomadik.c:1515:16: note:
'flags' was declared here
unsigned long flags;
The function is question was never changed but it appears
the semantic checker could previously determine that the code
path that would use the flags was going to either use it or
not, but now it can't for some reason. Just fix it up.
