Subject: [PATCH v17 0/3] add power control in i2c

Although in the most platforms, the power of eeprom
and i2c are alway on, some platforms disable the
eeprom and i2c power in order to meet low power request.

This patch add the pm_runtime ops to control power to
support all platforms.

Changes since v16:
 - request regulator in device instead of in the core.
 - control regulator only if it's provided.

Changes since v15:
 - Squash the fix[1] for v15.
