i2c: imx: when being a target, mark the last read as processed

Browse source

[ Upstream commit 87aec49936 ]

When being a target, NAK from the controller means that all bytes have
been transferred. So, the last byte needs also to be marked as
'processed'. Otherwise index registers of backends may not increase.
