davinci: make it possible to include clock.h and psc.h in assembly code
psc.h contains register defines for PSC module which need to be accessed in assembly code which helps the DA850/OMAP-L138 SoC go to sleep. Shutting down DDR clock using PSC is a part of the sleep procedure. Also, the PLL related hardware definitions in clock.h are needed in assembly code to bypass the DDR2 PLL.
