tpm/st33zp24: Add proper wait for ordinal duration in case of irq mode

In case the driver is configured to use irq, we are not waiting the answer
for a duration period to see the DATA_AVAIL status bit to raise but at
maximum timeout_c. This may result in critical failure as we will
not wait long enough for the command completion.
