This allows local and remote temp values to be added

and set alert thresholds. Fractional degrees are not
supported. DPTF support is not addressed.

This allows boards to detect the battery and return the correct temp
ranges, which will be needed for upcoming boards.
In the board-specific implementations, it's pretty much just moving
the fields from one const struct to another, so the impact is minor.

Smart batteries can report capacity in mAh or 10mW units. We forced
the units to mAh in charge_state.c's main loop, but that doesn't
guarantee that they're actually set before the capacity is read. It's
cleaner to check the capacity reporting mode when actually reading the
capacity.

The charge state machine asks for all of this stuff at the same time
anyway. Bundling it into a single function removes a number of
redundant (and painfully slow) I2C reads.
Also refactor the battery debug command so it doesn't have so many
local variables all in one function; it was consuming considerably
more stack space than any other debug command.
Spring still needs low-level access to the smart battery, so move the
two functions it needs directly into the Spring implementation.

This adds space for up to two ALS lux readings to be available to the AP
through the memory-mapped LPC region. If enabled, the values are updated
once a second.
The ALS will be reinitialized at every AP resume, since it's typically
unpowered otherwise. The reported value will be zero when the ALS is off.

Boot the AP, then from the EC console run "als" or just monitor the
memory-mapped region directly ("rw 0x40080780" on Samus), while pointing the
sensor at bright and dim areas. The value should change.

Bolt uses Link's battery, but doesn't override the smart battery charge

The smart battery status register holds some useful info. This displays it
along with all the other stuff.
This decodes the alarm and status bits, but not the error code, since that
field is only valid immediately after a failed i2c transaction (that's how
the battery indicates error). Since we do all sorts of automatic battery
probing in other threads, that value will never be reliable when we run the
"battery" console command.

The common/ subdir was getting cluttered. Move drivers for external

chipset_*.c to a new power/ directory.
This does not move/rename header files or CONFIG options. That will
be done in subsequent steps, since moving and modifying .c files in
the same CL is harder to review.
