i2c/tps65010: New-style driver updates, part 2
Switch the tps65010 driver into a "new-style" I2C driver, and convert all
of its in-tree users (board support for OSK, H2, H3) accordingly.
That accounts for most of the board-specific code in this driver; the
rest of that code is now moved into board-specific initcalls.
Also remove some of the many now-superfluous #includes.
