[PATCH v3 2/5] dt-bindings: media: arm,mali-c55: Describe DMA line-tick interrupts

[Linus Walleij <linusw@kernel.org>]

Mali-C55 exposes separate full-resolution and UV DMA writer line-tick
interrupts in addition to its combined core interrupt.

Describe these optional interrupts, keeping the core interrupt first and
requiring only that entry to preserve support for existing device trees.
Extend the example to show all three interrupts using mock interrupt
numbers.
