ram: rk3399: Simplify data training first argument
data training is using chan_info as first argument with
channel number as second argument instead of that use
dram_info as first argument so-that we can get the
chan_info at data training definition.
This was the argument handling is meaningful, readable
and it would help to add similar data training for
lpddr4 in future.
