rp2/machine_i2c: Use soft I2C only for len=0, and increase timeout.
The RP2040 I2C hardware can do writes of length 1 and 2, just not of length
0. So only use software I2C for writes of length 0, to improve
performance.
Also increase the software I2C timeout for zero-length writes to
accommodate the behaviour of a wider range of I2C devices.
Fixes issue #8167.
