Paul Walmsley 4cb49fec12 OMAP2+: powerdomain: fix bank power state bitfields
The bank power state bitfields in the powerdomain data are
encoded incorrectly.  These fields are intended to be bitfields,
representing a set of power states that the memory banks support.
However, when only one power state was supported by a given bank,
the field was incorrectly set to the bit shift -- not the mask.
While here, update some file copyrights.

The OMAP4 autogeneration scripts have been updated accordingly.
