rtc: at91sam9: Fix missing spin_lock_init()
The driver allocates the spinlock but not initialize it. Use spin_lock_init() on it to initialize it correctly. This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
