gpio: Add Spreadtrum EIC driver support
The Spreadtrum digital-chip EIC controller has 4 sub-modules: debounce EIC,
latch EIC, async EIC and sync EIC, and each sub-module can has multiple
banks and each bank contains 8 EICs.
Each EIC can only be used as input mode, and has the capability to trigger
interrupts when detecting input signals.
