[PATCH v2 14/18] media: rzg2l-cru: Add IRQ handler to OF data

[Tommaso Merciai]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Add `irq_handler` to the `rzg2l_cru_info` structure and pass it as part of
the OF data. This prepares for supporting RZ/G3E and RZ/V2H(P) SoCs, which
require a different IRQ handler. Update the IRQ request code to use the
handler from the OF data.
