media: imx-jpeg: Disable useless interrupt to avoid kernel panic
There is a hardware bug that the interrupt STMBUF_HALF may be triggered
after or when disable interrupt.
It may led to unexpected kernel panic.
And interrupt STMBUF_HALF and STMBUF_RTND have no other effect.
So disable them and the unused interrupts.
meanwhile clear the interrupt status when disable interrupt.
