Regulator: DA9052/53 regulator support v5

The Dialog PMIC has below featured regulators:- DA9052-BC - 4 DVS Buck converters 0.5V - 3.6V upto 1Amp. DA9053-AA/BX - 4 DVS Buck converters 0.5V - 2.5V upto 3Amp. DA9052/53 - 10 Programmable LDO's High PSSR, 1% accuracy.

This patch support all the DA9052 and Da9053 regulators. The output voltages are fully programmable via I2C or SPI interface. The platform data with regulation constraints is passed down from the board to the regulator.

Changes since v5
- Modify Kconfig to describe the config symbol
- Change file permissions - remove execute permission
- Line 43 - Adjust for 80 characters width
Changes since v4
- Add support for DA9053
- Correct the definition of macros DA9052_BUCK_ILIM_MASK
- Get current limit to return current limit in microA
- Correct the voltage selector value for Buck Peri above 3v
- Set the struct member regualtor->da9052 in probe() Changes since v3
- Corrected verify_range function
Changes since v2
- Check for current min_uA < 700000
- Corrected current conversions from mA to uA
