Derated timings are used to ensure that the memory chips keep operating
correctly at high temperatures. This adds code to support polling of the
chip operating state when high temperatures are measured on the chip and
change the refresh mode accordingly. Under very high temperatures, the
driver will switch to the derated tables to ensure proper operation of
the memory chips.

This patch includes the sequence for clock tuning and the dynamic
training mechanism for the clock above 800MHz.
And historically there have been different sequences to change the EMC
clock. The sequence to be used is specified in the EMC table.
However, for the currently supported upstreaming platform, only the most
recent sequence is used. So only support that in this patch.
Based on the work of Peter De Schrijver <pdeschrijver@nvidia.com>.
