i2c: Add a DM_I2C driver for the sun6i P2WI controller
This bus controller is used to communicate with an X-Powers AXP PMIC.
Currently, various drivers access PMIC registers through a platform-
specific non-DM "pmic_bus" interface, which depends on the legacy I2C
framework. In order to convert those drivers to use DM_PMIC, this bus
needs a DM_I2C driver.
Refactor the p2wi functions to take the base address as a parameter,
and implement both the existing interface (which is still needed in
SPL) and the DM_I2C interface on top of them.
The register for switching between I2C/P2WI/RSB mode is the same across
all PMIC variants. Move that to the common header, so it can be used by
both interface implementations.
