davinci: move PSC register definitions from psc.c to psc.h
The motivation behind the change is to use the same definitions in the assembly code responsible for suspending the SoC, a part of which is to clock gate the DDR2 clock. Note that the assembly code cannot invoke the C function meant for this. The main reason being that stack in DDR2 cannot be accessed while DDR2 clock is being clock gated.
