Vincent Palatin 94063c0f35 stm32: support DMA on I2C1 ...

Each I2C controller needs to use a fixed pair of DMA channels.
The former code was hardcoded for I2C2. We now use the board
configuration to decide between I2C1 and I2C2 DMA channels.

BRANCH=none
BUG=chrome-os-partner:15185
TEST=make BOARD=snow && make BOARD=spring && make BOARD=daisy
run on Spring and Snow and see we can communicate both with the PMU
(using "pmu" EC console command) and the AP (answering U-Boot host command)
