lpi2c: Add bus busy error handling

When doing "i2c dev 4; i2c probe" with ENET daughter card connected
on iMX8QXP MEK board, we met a i2c bus busy issue, that the BBF of
lpi2c always show busy, but the master is idle, and stop is detected
(SDF set).

This patch addes a handling to re-init the lpi2c master for this
case. Then the issue can be worked around.
