dma/amba-pl08x: check for terminal count status only
For some reason I can't figure out we're reading the PL080_INT_STATUS register instead of PL080_TC_STATUS when checking for the terminal count. The PL080_INT_STATUS is a logical OR between the error and terminal count status register and may not report what we want it to, especially if there is an error and a terminal count at the same time and the former is not lowered in time for the check in the TC register. Make sure we read what we're actually interested in.
