drm/amd/display: Validate irq source in DM IRQ handler
[Why]
dc_interrupt_to_irq_source() can return DC_IRQ_SOURCE_INVALID for an
unmapped src_id/src_data pair. The value was passed straight to
dc_interrupt_ack() and used to index the DM high/low handler tables.
[How]
Reject sources outside the valid range before using them.
