Baolin Wang 7bf0d7f622 gpio: eic: Add edge trigger emulation for EIC 
The Spreadtrum debounce EIC and latch EIC can not support edge trigger,
but most GPIO users (like gpio-key driver) only use the edge trigger,
thus the EIC driver need add some support to emulate the edge trigger
to satisfy this requirement.
