ish/ish5: add console in use timeout mechanism in low power managmentstabilize-12121.B
on ISH, uart interrupt can only wakeup ISH from low power state via
CTS pin, but most ISH platforms only have Rx and Tx pins, no CTS pin
exposed, so, we need block ISH enter low power state for a while when
console is in use.
we have two default timeout values for this mechanism:
1: after ISH boot, have 15 seconds window can input console commands
2: refresh 60 seconds timeout for console use after each console input
BUG=b:129246461
BRANCH=none
TEST=verified on arcada platform
