dm: pmic: add implementation of driver model pmic uclass
This commit introduces the PMIC uclass implementation.
It allows providing the basic I/O interface for PMIC devices.
For the multi-function PMIC devices, this can be used as I/O
parent device, for each IC's interface. Then, each PMIC particular
function can be provided by the child device's operations, and the
child devices will use its parent for read/write by the common API.
Core files:
- 'include/power/pmic.h'
- 'drivers/power/pmic/pmic-uclass.c'
The old pmic framework is still kept and is independent.
For more detailed informations, please look into the header file.
Changes:
- new uclass-id: UCLASS_PMIC
- new config: CONFIG_DM_PMIC
