[PATCH] gpio: eic: sprd: Fix the incorrect EIC offset when toggling

[Baolin Wang]

From: Bruce Chen <bruce.c...@unisoc.com>

When toggling the level trigger to emulate the edge trigger, the
EIC offset is incorrect without adding the corresponding bank index,
thus fix it.

Fixes: 7bf0d7f62282 ("gpio: eic: Add edge trigger emulation for EIC")
