chip/npcx/cec: Expose cec_isr to help linker
In LTO mode (which we use) the linker partitions the object files and
does some optimizations in parallel, including dead code elimination.
For DCE two criteria are used:
1. the symbol is used within the current partition
2. the symbol is exported
static void cec_isr() wasn't exported and if it ended up in a different
partition from the code created by DECLARE_IRQ, it was eliminated just
to be declared missing in the final link step.
