MLK-17357-2 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.
