mb/google/asurada: fix EC commands timeout 

The Asurada EC is using the large packet (256B) mode, and we were
seeing lots of timeout errors on various commands.

The AcceptTimeoutUs in EC SPI driver is hard-coded at 5000,
and that is too small for large packet running in 1M so we
should change EC SPI to the same value that kernel is using (3M).
