ram: k3-ddrss: do not touch ctrl regs during training
commit af7c33c103450e06aecf8adba8cbc8c522295be1 upstream.
During LPDDR initialization we will loop through a series of frequency
changes in order to train at the various operating frequencies. During
this training, accessing the DRAM_CLASS bitfield could happen during a
frequency change and cause the read to hang.
Store the DRAM type into the main structure to avoid multiple readings
while the independent phy is training.
