In the probe function of the bq20z75 driver, check for the presence of the
bq20z75. If there is no response from device, terminate the driver
initialization.

Generally boards define platform data structs as
__initdata. Due to this, it is not available in
the driver as a pointer. The driver needs to copy
the platform data to its context in order to use
it after _probe exits.

Need to enable detection, which is also blocking the unit conversion logic
after registering the power_supply.

Adding support for external power change notification. One problem found
is that there is a lag time before the sensor will return a new status.
To ensure that we only fire off the power_supply_changed event when the
status returned from the sensor is actually different, we delay sending
the the notification, and instead poll on it looking for a change. The
amount of time to poll is configurable via platform data.

Corrected temperature and time to empty/full conversions.
Temperature is in 0.1°C, time is in seconds.
Corrected units in comment. "Convert to µWh."

There are a few issues found around the battery not being present. If the
battery isn't present, then a few undesirable things happen. The first was
excessive reporting of failed properties. This was fixed by instead
returning ENODATA for all properties other than PRESENT if the battery
isn't present. That way the callers can identify the difference between a
failure and the battery not being there.
The next issue was in the suspend logic. It was found that if the battery
wasn't present, then it would return a failure, preventing the system from
going into suspend. If there is no battery present, the io is expected to
fail, so in that case, we shouldn't return the failure and just
acknowledge that it was expected.
I also found that when a gpio was used, i didn't maintain the internal
is_present state properly. I added a set of that to fix that.
Lastly, the code to see io's fail and figure out that the battery isn't
present when not using a gpio had a problem. In that code, it looked for
the read to fail and if it did, then handled it. The problem is that in
function to get the property, it first writes a value and that write can
fail, causing the code to never reach the logic after the read. Fix is
to move the logic till after the write.

The device table is required to load modules based on modaliases.
After adding the MODULE_DEVICE_TABLE, below entry will be added to
modules.alias:
alias i2c:bq20z75 bq20z75

With the support of platform data, now adding support for option i2c
retries on read/write failures. Ths is specified through the optional
platform data.

Adding support for an optional gpio for battery detection. This is
passed in through the i2c platform data. It also accepts another
field, battery_detect_present to signify the gpio state which means
the battery is present, either 0 (low) or 1 (high).

Adding support for charge properties for gas gauge.
Also ensuring that battery mode is correct now for energy as well as
charge properties by setting it on the fly.
I also added 2 functions to power_supply.h to help identify the units for
specific properties more easily by power supplies.

This patch adds properties to support devicekit power. Also, create IO
wrapper functions and fix some issues found while testing, including
unit conversions to match the power_supply types.
