Subject: [PATCH v2] media: imx-jpeg: Disable some unused interrupt
The interrupt STMBUF_HALF may be triggered after frame done.
It may led to system hang if driver try to access the register after
power off.
And interrupt STMBUF_HALF and STMBUF_RTND have no other effect.
So disable them and the unused interrupts.
Fixes: 2db16c6ed72ce ("media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder")
