mtd: dc21285: use raw spinlock functions for nw_gpio_lock
Since commit bd31b85960a7 (which is in 3.2-rc1) nw_gpio_lock is a raw spinlock
that needs usage of the corresponding raw functions.
This fixes:
drivers/mtd/maps/dc21285.c: In function 'nw_en_write':
drivers/mtd/maps/dc21285.c:41:340: warning: passing argument 1 of 'spinlock_check' from incompatible pointer type
spin_lock_irqsave(&nw_gpio_lock, flags);
