Jae Hyun Yoo 65d270acb2 media: aspeed: clear garbage interrupts
CAPTURE_COMPLETE and FRAME_COMPLETE interrupts come even when these
are disabled in the VE_INTERRUPT_CTRL register and eventually this
behavior causes disabling irq itself like below:

[10055.307344] Disabling IRQ #23

To fix this issue, this commit makes the interrupt handler clear
these garbage interrupts. This driver enables and uses only
COMP_COMPLETE interrupt instead for frame handling.
