samus: Updates from P2 build

- SPD GPIO table was changed from earlier builds and GPIO67 needs to be
swapped with GPIO69
- Hynix 8GB DRAM is actually x16 and needs updated geometry in the SPD
- Broadwell LPDDR3 at 1333 is not working in P2, remove the workaround
- In order to support both P2A and P2B with one firmware image we need
to read the EC board version and use the right SPD GPIO for bit3
- Touchpad I2C address changed to 0x4a/0x26

BUG=chrome-os-partner:29502
BRANCH=None
TEST=boot on P2A and P2B boards
