> This rework allows to address tow memory controllers. AT91SAM9263 and
> AT91SAM9G45 family have tow SDRAM or DDR/SDRAM controllers. Power management

> This patch modify the way RAM IP header files are implemented to allow
> access to registers of both controllers ; it also adds some macros.
> 
> We also modify the power management files to use those modified header files.
> Slow clock (assembly) and regular power management functions are synchronized
> for setting of RAM self-refresh procedure: 
> (lpr & ~AT91_DDRSDRC_LPCB) | AT91_DDRSDRC_LPCB_SELF_REFRESH
