I2C Reset Path: Add Poll of SCL High Before Issuing Stop Command
At the end of the I2C reset sequence, a 'stop' command is sent to
each port on the master that was reset. Before sending this 'stop'
command, a poll has been added such to check that SCL (clock line)
is high. This addresses a known issue with current TPMs.
