media: aspeed: remove IRQF_SHARED flag

Video Engine has a dedicated interrupt line so this driver doesn't
need to use IRQF_SHARED flag so remove it. Also, it'd be good for
following what Thomas recommended in the IRQF_ONESHOT support
patch like below:

"Note that for now IRQF_ONESHOT cannot be used with IRQF_SHARED to
avoid complex accounting mechanisms."
