npcx/lpc: Add debug command to trigger sci/smi/wake
This change adds console command to trigger sci/smi/wake based on the
user-provided argument. This command is enabled only when DEBUG_LPC is
set to 1. It was very helpful while debugging b:78497502 where I could
trigger the interrupts to check communication between AP and EC.
BUG=b:78497502
BRANCH=None
TEST=Verified by enabling DEBUG_LPC that sci/smi/wake are generated as
expected.
