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
