1. Add a new config option to define history buffer length. This
allows boards to override this option if required.
2. Get rid of unused PORT80_POLL_PERIOD macro
BUG=None

TEST=Verified that all port80 messages from a boot-up or S3 resume are
present in port80 history buffer.

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).

Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.
We're never going to use this, let's just get rid of it.

The only boards that had a port 80 task were the ones using the MEC1322.
Since that EC now has a dedicated timer interrupt configured for port80
writes, we can remove this code that was providing the port 80 task.
Additionally, the config option CONFIG_PORT80_TASK_EN is removed.

port80 task polling prevents the EC from entering low power states and
isn't useful when the AP isn't running. Therefore, when
CONFIG_PORT80_TASK_EN is enabled, only enable the port80 task when
entering S0, and disable it when leaving S0.

With mec1322's EMI set to decode IO 0x800, it does not have any other
interfaces to support POST code via IO 0x80.
This change is to enable Port80 POST code support via polling method.
Limitation:
- POST Code 0xFF will be ignored.
- POST Code frequency is greater than 1 msec.

- 'port80 intprint' toggles printing port 80 codes in interrupt
handler (turning that off speeds up port 80 capture a bit, if you're
sending port 80 codes very rapidly)
- 'port80 flush' flushes the log buffer
- log buffer expanded to 256 entries
- log buffer tracks S3->S0 power state transitions, so you can tell
where each boot starts
This uses ~500 bytes more RAM on the EC, but we've got piles of RAM
(with this change we're using 17KB out of 32KB).
