Add a timeout mechanism when waiting for the RXDV (Receive Data
Valid) status bit to be set before reading data from the FIFO.
This prevents infinite polling loops that could occur if the
hardware doesn't respond as expected.
The timeout is set to 1000ms (CDNS_I2C_RXDV_TIMEOUT_MS) and uses
the wait_for_bit_le32() function to poll the status register. If
the timeout expires, an error code is returned.
