Marek Vasut 6ef540d50f ARM: renesas: Factor out DRAM setup on R-Car Gen3
Pull DRAM layout configuration code into rcar-common.c instead of
having it in multiple copies across board files. This poses no
change for Salvator-X/XS, ULCB and Ebisu boards, however it adds
a bit of extra code for Draak and Eagle boards, which now gain
the capability of being passed in the DRAM layout by the ATF.
