misc: rockchip decompress: Enable IRQ when storage is spi-nand in SPL

1. If you need to auto trigger an interrupt to wake up rootfs
unpack when kernel DECOM driver is initialized, you need to enable
DECOM interrupt in SPL.
2. SPL may decompress multiple packages, and interrupts need to be
cleared first to prevent from being triggered when it enters kernel
without completing the decompression.
