The INT_BUFWEN IRQ often arrives with other bits set too. If they are not cleared, an additional IRQ can be triggered, sometimes also after the MMC request has already been completed. This leads to block I/O errors. Earlier Teppei Kamijou also observed these additional interrupts and proposed to explicitly wait for them. This patch chooses an alternative approach of clearing all active bits immediately, when processing the main interrupt.
