ee8076ed3e power_supply: Add a charge_type property, and use it for olpc driver
This adds a new sysfs file called 'charge_type' which displays the
type of charging (unknown, n/a, trickle charge, or fast charging).

This allows things like battery diagnostics to determine what the
battery/EC is doing without resorting to changing the 'status' sysfs
output.

b294a290d2 Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL"
This reverts commit 8efe444038 and
4cbc76eadf.

Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging
battery/EC problems, and was upset that it was removed.  This readds it.

8e552c36d9 power_supply: add CHARGE_COUNTER property and olpc_battery support for it
This adds PROP_CHARGE_COUNTER to the power supply class (documenting it
as well).  The OLPC battery driver uses this for spitting out its ACR
values (in uAh).  We have some rounding errors (the data sheet claims
416.7, the math actually works out to 416.666667, so we're forced to
choose between overflows or precision loss.  I chose precision loss,
and stuck w/ data sheet values), but I don't think anyone will care
that much.
