media: rkisp1: Fix IRQ handler return values

Browse Source 
The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.

Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.
