In burst read flow, we need to wait CCI irq once one set data is read, but the fifo may has new data what can be read immediately and don't need to wait the irq. This change also optimize the irq processing, we can reset irq mask first, then process the irq status, it can avoids some timing issue, e.g. the read context runs too quickly, then read context enable the read threshold bit in irq mask1, but irq context runs late, then irq context clear the read threshold, then we can't receive read threshold again.
