veyron: mickey sdram-lpddr3-samsung-2GB.inc now 40 Ohm

Browse source 
The value of 0x4 (60 Ohm) apperas to be causing lots of problems.
Since 0x1 (34.3 Ohm) was _almost_ right, let's try 0x2 (40 Ohm) and
hope it's the sweet spot.

BRANCH=None
BUG=chrome-os-partner:43626
TEST=My mickey now boots up
