x86: ivybridge: Provide a dummy SDRAM init for 64-bit

We don't support SDRAM init in 64-bit mode since it is essentially
impossible to get into that mode before SDRAM set up. Provide dummy functions
for now. At some point we will need to pass the SDRAM parameters through from
SPL.

The memory reference code takes a very long time to 'train' its SDRAM
interface, around half a second. To avoid this delay on every boot we can
store the parameters from the last training sessions to speed up the next.

Add an implementation of this, storing the training data in CMOS RAM and
SPI flash.
