This changes memory to only do CA training with one pattern,
0xfffff/0x00000 and to also make sure CA training waits for all of the
captures during training.

To enable DDR Dynamic Voltage and Frequency Scaling (DVFS) we need to
train alternative configurations first, so do the training and store the

PHY_PER_CS_TRAINING is being enabled when DDR frequency >= 666.
For per cs training, the controller should consider the PHY
delay line switch time and there should be more cycles to
switch the delay line, so update the W2W_DIFFCS_DLY_ value
from 0x1 to 0x5.

We found some boards are not stable when sdram is run at 933Mhz.
Before we can fix it, we need to lower the sdram frequency to 800MHz.
In this patch we modify the DQS delay from 0x280 to 0x260 and extend
the DQS window.

This patch changes Gru SDRAM parameters from structures that just get
compiled into the romstage to individual CBFS files. This allows us to
only load the parameter set we need for the board we're booting from
flash, which reduces our boot time and the SRAM memory footprint
required to hold the romstage.
TEST=Booted Kevin.
