For sensor_range and sensor_odr parameters, since the host doesn't know
what are valid values for the parameter, the host can specify to round
up or down to the nearest valid value. For example, the host can specify
to set the output data rate to at least 100Hz, and the EC will return
the closest valid output data rate that is at least 100Hz.

After running this I verified on the EC console that all the parameters
were set appropriately. I tested the EC sampling rate was 1000ms by
running lidangle on and making sure samples were displayed roughly every
second. I verified the sensor odr and range by defining
CONFIG_CMD_ACCELS and typing:

This replaces the obsolete and temporary (ha!) EC_CMD_CHARGE_DUMP host
command with EC_CMD_CHARGE_STATE. This is used to monitor and adjust the new
charge state implementation, including any board-specific customizations.
This command is a single catch-all command with multiple subcommands
(similar to EC_CMD_LIGHTBAR_CMD) so that we don't have to keep adding new
top-level host commands just to support incremental changes.

From the AP, try these commands:

ectool chargestate param
ectool chargestate param <NUM>

Watch the EC console and use its "chg" command to verify the effects of
setting various params.
Note: the Samus-specific fast-charging profile override is param 0x10000.
You can check it with the EC console "fastcharge" command.

If the host somehow fails to see an edge on the keyboard IRQ line, it
won't read the 8042 data register. The EC won't ever send another
IRQ, because it only does so after filling the register. So the
keyboard will hang.
Work around this with a retry mechanism. If the AP hasn't responded
after 3 additional keyboard events, generate another IRQ. So a stuck
key will get unstuck if you tap it a few times. That's reasonable,
and matches what people do already if they have a sticky key due to
crud accumulating in the keyboard.
I've tested this when the system is booted to the OS. I don't see any
additional IRQs generated on the EC console ("KB extra IRQ"), so the
host is keeping up with the keyboard input stream.
If I'm in dev or recovery mode and bang on the keyboard right after
powering the system on (when the BIOS isn't yet paying attention to
the keyboard), I can see extra IRQs generated. This shows the retry
mechanism is working. The extra IRQs have no negative effect on the
boot process, and the keyboard works normally when the OS does
eventually boot.

This is a complete rewrite of the charge_state task used by x86 platforms.
Rather than having a bunch of state-specific functions, each with their own
error handling and special cases, this is organized like so:
Forever:
1. Read everything we can from the battery and charger.
2. Figure out what we'd like to do (including error handling).
3. Allow for customization to override that.
4. Do it.
Things I need to file bugs for are marked with "TODO(wfrichar)". I'll file
the bugs after this CL goes in, so that they'll have something relevant to
refer to.

This adds two battery parameters that need to be monitored constantly:
remaining_capacity and full_capacity (that one only changes occasionally,
but we have to notify the AP when it does).
It also adds the is_present field to indicate whether the battery is
physically present or not (when we can tell), so we know whether to try to
wake up a deep-discharged battery.
Along with that, we clean up the error flags to provide indication of which
fields were unable to be read, and replace the manual logical-or of all
errors as they were set with a bitmask (BATT_FLAG_BAD_ANY).
No functionality is changed, only new & better information is provided for
