3dd6e71828 power: Move EC_CMD_GSV_PAUSE_IN_S5 handler to common code
The same code exists in four (soon to be five!) different power
sequencing drivers, so move it up to common.

BUG=None
TEST=Manual on Samus. Run "pause_in_s5 on" on EC console, verify that
system stops in S5 on shutdown. Run "pause_in_s5 off" on EC console,
verify that system again goes to G3 on shutdown.
BRANCH=None

ffac23c0ea Add cprints() and ccprints()
Our code base contains a lot of debug messages in this pattern:
  CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().

cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)

This saves us hundreds of bytes in EC binaries.

930b41e6a9 Allow AP to set wireless power state in suspend
Previously, the AP could only set the current wireless power state.
It couldn't determine what the EC would do in S3, nor could it get the
current wireless power state.  Extend the wireless command to do so,
and add an EC console command to aid in debugging.

BUG=chrome-os-partner:25655
BRANCH=rambi
TEST=manual; expected numbers are from EC 'wireless' command
  AP off -> 0x0, 0x9
  AP on -> 0xd 0x9
  AP suspended -> 0x9 0x9
  AP on -> 0xd 0x9
  ectool wireless 0x1 -> 0x1 0x9
  ectool wireless 0xd -> 0xd 0x9
  ectool wireless 0 0 0 0 -> 0xd 0x9 (and prints 0xd 0x9 to root shell)
  ectool wireless 5 -1 -1 0 -> 0x5 0x9
  AP suspended -> 0x1 0x9 (doesn't turn on 0x8, just turns off 0x4)
  AP on -> 0xd 0x9
  ectool wireless 0 0 0 -1 -> 0xd 0x0
  AP suspended -> 0x0 0x0
  AP on -> 0xd 0x9

44feb4b4e7 Fix leaving SUSP_VR_EN enabled if S5 rails fail to come up
We noticed this on a baytrail board, but the same problem exists in
haswell as well.  And while looking there, found that we skipped the
S5G3 state if the 5V rail failed to come up.

Fortunately, these are all rare corner cases; rails will always come
up on a good system.  So this only affects systems during bringup and
factory, not devices in the field.

BUG=chrome-os-partner:24915
BRANCH=rambi (and technically haswell, but may not be worth merging)
TEST=Try booting a system with a bad power rail; see that SUSP_VR_EN=0
     after the system fails to boot.

6ab8e91658 cleanup: Remove checkpatch warnings
This make minor syntactic changes and renames some camel-cased symbols
to keep checkpatch from complaining.  The goal is to reduce the
temptation to use 'repo upload --no-verify'.

This is a big furball of find/replace, but no functional changes.

7e78087a91 lm4: Fixes low power bug after a sysjump
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.

8cf03ac056 Move source files to driver/ and power/ subdirs
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.
