Bill Richardson 1d2845d2db Add EC_MEMMAP_ALS, update it once per second ...

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.

BUG=chrome-os-partner:23380
BRANCH=samus
TEST=manual

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.
