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

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.

Changes in v5:
- fix commit description: S2DOS05 in capital letters
- fix commit description: only 1 sub device will be
  added in subsequent patches.
