[PATCH v6 2/3] mfd: sec-core: add s2dos05 support

[Dzmitry Sankouski <dsankouski@gmail.com>]

S2DOS05 is a panel/touchscreen PMIC, often found in
Samsung phones. We define regulator sub-device for which driver will
be added in subsequent patch. The device also has ADC for power and
current measurements.
