out of usb_pd_config.h and into board.h. This cleans up the

The fans on samus have a recommended minimum duty cycle of 20%
while running, but 30% in order to start. We've been using the
EC's built-in fan controller for the start requirement, but it
has a minimum fast-start duty cycle of 50%. It turns out that
that speed is noticeably noisy.
This change handles the startup with logic in the EC instead, so
that the fan only tries to spin at 30% initially (or if it drops
too much below the minimum turning speed).

Boot the system, let it idle with the browser windows closed, the
browse a bit, then idle. Listen for changes to the fans.
Before, I could hear the fans kick in and out as the AP load
changed. Now it's much quieter.

Design Goals:
1. Every time the AP boots, the same default sensor settings are configured.
2. If the AP goes to suspend (S3) and wakes back up (S0),
then the AP sensor settings will be restored.
3. In S3 and in S5, only sample specific sensors that are needed.

PULSE and TEST sequences are not used anywhere. Remove them to save
flash space. Also, fix msleep(MSEC) calls in the unit test; it's
essentially usleep(SECOND) written in an incorrect way.

This is mostly the same as previous commits, but with increased delay.
Previously, we have short delays (e.g. 3ms) which is too short and may
cause instability.
Now that we have slowed down the time when running unit tests and
increased the delay, this shouldn't cause problems anymore.

When a timing sensitive test run on a heavily loaded system, sometimes a
task runs for longer than it usually does and causes the test to fail.
All the timing requirements in the unit tests are trying to verify the
various delays in our codebase, and mostly we don't care about the time
taken by active running code (as they are very quick.) To improve the
stability of tests, let's slow down the time. To a test, it's as if the
code runs faster. If a test uses udelay() and exceeds the 10-second time
limit, we can make that single test faster by setting the time scale.

Previously there was no way to remove multiple units at a time
from the queue, and the queue was wasting an entry to disambiguate
full from empty. There was also no way to get the free entry
count from the queue, only the ability to query if it was above
a required amount. The queue was also storing its constant
compile time configuration as well as its dynamic state in the
same structure. This wasted RAM on configuration information
that doesn't change.
This refactor fixes these issues, making the queue suitable for
use in the new USART stream driver.
