Move DaVinci PSC support from board/* to cpu/* where it belongs.
The PSC module manages clocks and resets for all DaVinci-family
SoCs, and isn't at all board-specific.

Taken all the duplicated code for enabling common modules and apply
software workarounds from the board specific code into common
functions. Also added comments explaining the workarounds
(from TI errata documents) and replaced some numerical bit numbers
with more meaningful defines.
