i2c: riic: fix restart condition

Browse source

[ Upstream commit 2501c1bb05 ]

While modifying the driver to use the STOP interrupt, the completion of the
intermediate transfers need to wake the driver back up in order to initiate
the next transfer (restart condition). Otherwise you get never ending
interrupts and only the first transfer sent.
