i2c: imx: fix imx driver to work though signal is pending

Interrupt a test application for I2C based mc13xxx driven
touch panel, SIGINT, causes open event file descriptor to be
closed, which in turn causes I2C activity to mask PMIC local
interrupts. This eventually ends up in i2c_imx_bus_busy to
wait for some busy flag to toggle, but while waiting it would
find a signal pending and break. The final symptom is the
device is not closed down cleanly and thus not reopenable.

Do without check for pending signal.
