Wenhua Lin f1ba5bf9e0 gpio: eic-sprd: Clear interrupt after set the interrupt type ...

[ Upstream commit 84aef4ed59705585d629e81d633a83b7d416f5fb ]

The raw interrupt status of eic maybe set before the interrupt is enabled,
since the eic interrupt has a latch function, which would trigger the
interrupt event once enabled it from user side. To solve this problem,
interrupts generated before setting the interrupt trigger type are ignored.
