ryu: Add 4 LPDDR3 SDRAM BCTs

Hardware / Coreboot - Aaron Durbin [chromium.org] - 25 March 2015 16:31 UTC

These are used by the LPDDR3 code in sdram.c.

Based on the schematic and email, I've filled in 4 slots in sdram_configs.c. My A44 returns RAMCODE 0 (using only bits 1:0) for Samsung SDRAM. I haven't tested the other 2 types of RAM (Hynix and Micron). The 4th slot is a fallback slow Micron config.

Previously existing configurations were dropped.

BUG=chrome-os-partner:29921 BUG=chrome-os-partner:31031 BRANCH=None TEST=Built for rush and rush_ryu.
