Refactored keyboard scan enable/disable flag such that it is a mask of
potential disable sources. When all disable sources are off, scanning is
enabled, otherwise scanning is disabled. This fixes a recently introduced
bug in which enabling/disabling keyboard scanning due to lid angle in S3
was interfering with enabling/disabling keyboard scanning due to power
button. This also allows for easy expansion for future causes for disabling
keyboard scanning.

The XPSHOLD is not floated. It connects to +1.8V_VDDIO, which indicates
high when AP is on. So, bring it back.
Also remove the duplicated GPIO definition (GPIO_PWR_LED1).

Refine the GPIO list according to the schematic. Comment out the XPSHOLD in
power/tegra.c for compiling. Will fix later.

Due to power topology, PP5000 needs to be enabled as soon after
PP3300_DSW as possible. Since PP3300_DSW is what powers the EC, the
EC needs to turn on PP5000 by default and leave it on.

TEST=reboot ap-off (this boots the EC without doing AP power sequencing)

This fixes a bug in which after a sysjump, the sleep_mask is
reset, and the EC is allowed to go into a low power mode even
though the AP is still running. This causes numerous problems,
must notable of which is that a flashrom write fails with an
EC protocol mismatch error.
BUG=chrome-os-partner:23645
BRANCH=none
TEST=Execute a flashrom write and make sure the system does not
use the low power code immediately after.

The common/ subdir was getting cluttered. Move drivers for external
components to a new driver/ tree, and move what used to be called
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.
