Texas Instrument's TPS65910 PMIC contains 3 buck DC-DC converts, one boost DC-DC converter and 8 LDOs. This patch implements driver model support for the TPS65910 PMIC and its regulators making the get/set API for regulator value/enable available. This patch depends on the patch "am33xx: Add a function to query MPU voltage in uV" to build correctly. For boards relying on the DT include file tps65910.dtsi the v3 patch "power: extend prefix match to regulator-name property" and an appropriate regulator naming is also required.

Changes in v2: - move information about regulator supply power from the PMIC to the regulator driver which greatly simplifies and streamlines the code of both drivers (thanks Simon!) - use dev_get_uclass_platdata() to get the regulator constraints instead of reinventing the wheel and reading them from the DT - make pmic_tps65910_write() and pmic_tps65910_read() return the results of the i2c operation instead of obscuring it - generally review and eventually fix return values - modify regulator description in Kconfig - get_ctrl_reg_from_unit_addr() uses a lookup array instead of a switch statement - rename some local functions to prevent confusion with generic functions - reformatting code for better readability
