Simon Glass 0e42faf85b i2c: Display reason for each timeout ...

There are a lot of timeous in the i2c driver. When one occurs, print
out the number of it so that the root cause can more easily be
examined.

BUG=chrome-os-partner:10888
TEST=manual:
Lock up the i2c bus from the AP by running the kernel without bus
arbitration doing i2c traffic:

while true; do i2cdump  -f -y 4 0x48; done >/dev/null

and using 'pmu 100' on the EC.

Then see that a timeout error is printed, for example:

i2c wait_status timeout type 2, 101387 us
