port80: Disable default print of port80 messages in interrupt context
1. Add a new config option CONFIG_PORT80_PRINT_IN_INT which is
disabled by default to disable printing of port80 messages in
interrupt context.
2. If CONFIG_BRINGUP is defined, redefine CONFIG_PORT80_PRINT_IN_INT
to enable printing of port80 messages in interrupt context for boards
that are in bringup phase.
3. If print_in_int is disabled, add a deferred call to dump port80
buffer to EC console 4 seconds after the last port80 message is
received.
BUG=b:64196191
BRANCH=None
TEST=Verified following:
1. make -j buildall
2. Port80 messages are not printed by default on Soraka
3. Port80 buffer is dumped 4 seconds after last port80 message, if
BIOS is stuck for 4 seconds, in recovery mode and when reboot from AP
console.
4. Boot time on soraka went down from ~1.59seconds to ~1.45 seconds in
EC reboot case (savings of ~140ms).
