Add device tree data for regulator via tps6507x mfd device
in da850-evm.
Applies on top of v3.9-rc1 of linus tree.
Tested on da850-evm device.
Test procedure followed as below:
Once device boots up, issue command as:
$for reg in /sys/class/regulator/*; do echo $reg `cat $reg/name`
`cat $reg/state` `cat $reg/microvolts`; done
This command will print all available regulators with its name,
status (enabled/disabled) and voltages(in microvolts) like as below:
/sys/class/regulator/regulator.1 VDCDC1_3.3V enabled 3300000
/sys/class/regulator/regulator.2 VDCDC2_3.3V enabled 3300000
/sys/class/regulator/regulator.3 VDCDC3_1.2V enabled 1200000
/sys/class/regulator/regulator.4 LDO1_1.8V enabled 1800000
/sys/class/regulator/regulator.5 LDO2_1.2V enabled 1200000
Note: Some of patches in this series are already accepted and
residing in v3.9-rc1 kernel. These patches are as follows:
1. mfd: tps6507x: add device-tree support.
2. regulator: tps6507x: add device tree support.
3. ARM: davinci: da850: add DT node for I2C0.

Add device tree data for tps6507x regulator by adding
all tps6507x regulator nodes. Regulators are initialized
based on compatible name provided in tps6507x DT file.
All tps6507x PMIC regulator device tree nodes are placed
in a separate device tree include file (tps6507x.dtsi).
tps6507x.dtsi file is created using datasheet
http://www.ti.com/lit/ds/symlink/tps65070.pdf
Tested on da850-evm.

Add tps6507x regulator device tree data to da850-evm by
adding regulator consumers with tightened constraints
and regulator-name.TPS6507x regulator handle can be obtained
by using this regulator name.
Regulator constraints are added as per da850 board file.
Regulator names are given as per maximum output voltage the
regulator is capable to provide.
for e.g. regulator name for dcdc1 is "VDCDC1_3.3V".
Also, add tps6507x PMIC I2C slave device under I2C0 node.
Tested on da850-evm.

I would like to take this series via the davinci tree to manage
dependencies with rest of the DT patches. Any comments/objections on
this series? It will be nice to get your Acked-by/Reviewed-by.
