Subject: [PATCH v3 22/37] irqchip: davinci-aintc: move the driver to drivers/irqchip

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

The aintc driver has now been cleaned up. Move it to drivers/irqchip
where it belongs. There's no device-tree support for any dm* board so
there's no IRQCHIP_OF_DECLARE() - there's only the exported init
function called from machine code.
