The port 80 task just polls every 1ms until disabled when the system
goes into suspend. Therefore, this commit configures a 1ms timer
interrupt that will be used for the port 80 writes instead of using an
entire task. This saves task stack space as well as context switches.

If the ALS is not enabled in S3/S5 states then it will generate
errors when trying to read so should be gated.
This could be done with a check for chipset_state or adding a
new CONFIG_ALS_POWER_GPIO to check. However the ALS is also not
needed when the host is in S3/S5 yet the task continues to run
in the background every 1 second.
This commit adds a new task enable/disable hook to disable the
task when the system is suspended and enable the task when it
is resumed.
In order to fit this new task in glados the als console command
is guarded by a new config option. Since this is not a very
frequently used/needed console command it is disabled by default.
And finally the kunimitsu and strago boards try to enable ALS
but they never actually enabled the ALS task so this new code was
failing to build because TASK_ID_ALS did not exist. Also samus
was enabling it but as TASK_NOTEST so tests will fail, though
they are disabled globally on samus.

TEST=enable ALS on glados and successfully build and use it,
also successfully build EC and tests for kunimitsu, strago,
and samus which are the other boards that use the ALS task.

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.
BUG=chrome-os-partner:39386
TEST=Verified Port80 POST code is captured in EC console.
Verified "port80 task" console command will disable/enable Port80 task.
Verified "port80 poll" will get the last Port80 POST code.
