Subject: [PATCHv4 5/11] REGULATOR: Removal of testing framework and redundancy

REGULATOR module of the device driver for DA9052 PMIC device from Dialog
Semiconductor.

Changes made since last submission:
. registration of regulator driver is done via MFD
. removal of driver test framework
. removal of redundant printk and comments
. removal of redundant headers

Linux Kernel Version: 2.6.34
