[PATCH 3/3] ram: rk3399: Conduct memory training at 400MHz

Currently the default initialisation frequency is 50MHz. Although this does appear to be suitable for some LPDDR4 RAM chips, training at this low frequency has been seen to cause Column errors, leading to Capacity check errors on others. Here we force RAM initialisation to happen at 400MHz before
