Peter Ujfalusi 827ed9aef2 OMAP3: Move common twl configuration to twl-common 
Reduce the amount of duplicated code by moving the common
configuration for twl4030/5030/tpsxx to the twl-common file.
Use the omap3_pmic_get_config function from board files to
properly configure the PMIC with the common fields.
