qcacld-3.0: Support for configuring voltage corner mode

This change adds support for configuring voltage corner mode
thorugh INI parameter. User will provide a bitmap which will
be passed on to the FW during initialization. In this bitmap,
each pair of bits till BIT27 correspond to different phymode,
bw combination. Bit values signify voltage corner configuration.
