mfd: add base support for Dialog DA9030/DA9034 PMICs
DA9030 (a.k.a ARAVA) and DA9034 (a.k.a MICCO) are PMICs designed by Dialog Semiconductor, usually found on PXA-based platforms. These PMICs are I2C-based, multi-function devices, usually with LEDs, PWMs for backlight, BUCKs and LDOs, ADCs and touchscreen controller (on DA9034). This is the base support for the I2C operations, event registration and handling, sub-devices management.
