ARM: SMDK6410: Add initial support for WM1192-EV1 PMIC board
The Wolfson Microelectronics 1192-EV1 is a plug in module for the SMDK6410 providing power using a WM8312 PMIC. This patch provides initial hookup sufficient to initialise the board, though not all features are fully described yet. As part of this supplies for the system that are provided as a single supply by one of the currently merged PMIC boards are factored out so they can be reused between different regulators.

Enabling this option will build support for this module into
