Add dt support for the pmu device tps62360 and
Add binding documentation with example.
With this patch driver will support both device-tree and
non-device tree registration.

Convert platform data member regulator_init_data to pointer type.
This will avoid the copy of entire regualator init data into
platform data member when adding dt support and it can be achieve
by simple assignment:
pdata->init_data = of_get_regulator_init_data(dev, dev->of_node);

Fix multiple stylistic issue like:
- The print message should be not break into multiple line.
- line gap after variable declaration and statement.
- checkpatch error.
- some typo.
Some enhancement on error message printing to print error value
also along with proper text.
Avoid voltage_base conversion to microvolts every time.
Put init functions in init section.
Using efficient function inplace of calling multiple function
to reduce the code size.

Settling time is require when there is voltage output change.
Implement set_voltage_time_sel() callback which returns delay time
for voltage change to settle down to new value.

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.
For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.
The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

According to the datasheet[1], tps62360 is register compatible with tps62362.
tps62361B is register compatible with tps62363.
Thus this patch adds support for tps62362 and tps62363.
