stm32: do not enable interrupts on I2C1
We don't have any interrupt handler for I2C1, so enabling of the I2C1
interrupts will just end up triggering a panic everytime the interrupt
fires.
By the way, I2C1 is used as master and all communications happen without
using the I2C interrupt.

BRANCH=spring
BUG=chrome-os-partner:18499
TEST=On Spring, run EC flashing in a loop from the AP
while true
do
flashrom --fast-verify -p internal:bus=lpc -w ec.bin
flashrom --fast-verify -p internal:bus=lpc -w ec_autest_image.bin
done
and check that we always succeed and have no panic.
