stm32: Reduce keyboard scan period from 10ms to 3ms
Experimentally it is possible to press a key on snow for only 4.8ms.
We should aim to scan more frequently to catch those who only just
touch the keys, or type very quickly.
It takes a little over 2ms to complete a keyboard scan at present.
We shold aim to reduce this, but for now, it seems safe to reduce the
default scanning frequency to 3ms.
BUG=chrome-os-partner:12179
TEST=manual
Type on keyboard on snow in browser, and see that we still get results
and the EC is stable.
