Subject: [ARM] SMDK6410: Support WM1190-EV1 PMIC board

The SMDK6410 supports pluggable PMIC boards. One such board is the
Wolfson Microelectronics 1190-EV1 for the WM8350 PMICs. This patch
introduces initial support for this module. Further patches will
add additional integration with the system as support for the
S3C6410 and other devices on the system improves.
