[PATCH v3 17/18] ram: rk3399: Enable sdram debug functions

[Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx>]

This would help to debug the sdram base parameters while
debugging existing chip or while supporting new sdram type.

It require explicit enablement of CONFIG_RAM_ROCKCHIP_DEBUG
for showing the debug prints.
