dt-binding: regulator: rpmh-regulator: define RPMh sets and regulator modes 



Add #define constants for RPMh set and PMIC regulator mode
specification.  These can be used for rpmh-regulator device tree
node properties.

 *

 * %RPMH_REGULATOR_MODE_PASS:	Pass-through mode in which output is directly

 *				tied to input.  This mode is only supported by

 *				BOB type regulators.

 * %RPMH_REGULATOR_MODE_RET:	Retention mode in which only an extremely small

 *				load current is allowed.  This mode is supported

 *				by LDO and SMPS type regulators.

 * %RPMH_REGULATOR_MODE_LPM:	Low power mode in which a small load current is

 *				allowed.  This mode corresponds to PFM for SMPS

 *				and BOB type regulators.  This mode is supported

 *				by LDO, HFSMPS, BOB, and PMIC4 FTSMPS type

 *				regulators.

 * %RPMH_REGULATOR_MODE_AUTO:	Auto mode in which the regulator hardware

 *				automatically switches between LPM and HPM based

 *				upon the real-time load current.  This mode is

 *				supported by HFSMPS, BOB, and PMIC4 FTSMPS type

 *				regulators.

 * %RPMH_REGULATOR_MODE_HPM:	High power mode in which the full rated current

 *				of the regulator is allowed.  This mode

 *				corresponds to PWM for SMPS and BOB type

 *				regulators.  This mode is supported by all types

 *				of regulators.
