pinctrl: samsung: Protect bank registers with a spinlock
Certain pin control registers can be accessed from different contexts,
i.e. pinctrl, gpio and irq functions. This makes the locking provided by
pin control core insufficient.
This patch adds necessary locking using a per bank spinlock as it was
done in the old Samsung GPIO driver.
