gpio: aspeed: Convert aspeed_gpio.lock to raw_spinlock
The gpio-aspeed driver implements an irq_chip which need to be invoked
from hardirq context. Since spin_lock() can sleep with PREEMPT_RT, it is
no longer legal to invoke it while interrupts are disabled.
This also causes lockdep to complain about:
[ 0.649797] [ BUG: Invalid wait context ]
because aspeed_gpio.lock (spin_lock_t) is taken under irq_desc.lock
(raw_spinlock_t).
Let's use of raw_spinlock_t instead of spinlock_t.
