regulator: add MAX8907 driver
The MAX8907 is an I2C-based power-management IC containing voltage regulators, a reset controller, a real-time clock, and a touch-screen controller. The original driver was written by: * Gyungoh Yoo <jack.yoo@maxim-ic.com> Various fixes and enhancements by: * Jin Park <jinyoungp@nvidia.com> * Tom Cherry <tcherry@nvidia.com> * Prashant Gaikwad <pgaikwad@nvidia.com> * Dan Willemsen <dwillemsen@nvidia.com> * Laxman Dewangan <ldewangan@nvidia.com> During upstreaming, I (swarren): * Converted to regmap. * Allowed probing from device tree. * Reworked the regulator driver to be represented as a single device that provides multiple regulators, rather than as a device per regulator. * Replaced many regulator ops with standard functions. * Added ability to specify supplies for each regulator. * Removed the WLED regulator. If/when we expose this in the driver, it should be a backlight object not a regulator object. * Renamed from max8907c->max8907, since the driver covers at least the C and B revisions. * General cleanup.
