rockchip: Break out common dram code for rk3399
This renames dram.c and dram.h to dfs.c and dfs.h respectively. This is to make room for common functionality between frequency scaling and suspend code for the DRAM in a pair of common files named dram.c and dram.h. It also removes a duplicate enum definition from dram_spec_timing.h Change-Id: Ibfa1041f8781401f9d27901fe8c61862bcb05562 Signed-off-by: Derek Basehore <dbasehore@chromium.org> Signed-off-by: Caesar Wang <wxt@rock-chips.com>
