[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.

	  The Wolfson Microelectronics 1190-EV1 is a WM835x based PMIC

	  and audio daughtercard for the Samsung SMDK6410 reference

	  platform.  Enabling this option will build support for this

	  module into the kernel.  The presence of the module will be

	  detected at runtime so the the resulting kernel can be used

	  with or without the 1190-EV1 fitted.
