i2c: iproc: Add i2c repeated start capability

Browse source

Enable handling of i2c repeated start. The current code
handles a multi msg i2c transfer as separate i2c bus
transactions. This change will now handle this case
using the i2c repeated start protocol. The number of msgs
in a transfer is limited to two, and must be a write
followed by a read.
