Hi All,

This patch series aims to drop using platform_get_resource() for IRQ types
in preparation for removal of static setup of IRQ resource from DT core
code.

Dropping usage of platform_get_resource() was agreed based on
the discussion [0].

patch/20211209001056.29774-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

While doing the above just noticed the code can be simplified
so introduced patch 2/2 to use devm_platform_ioremap_resource().

Cheers,
Prabhakar
