Add support for AM64 SoC. 2. Minor improvement: use platform_get_irq(). [miquel.raynal@bootlin.com: A first commit introduced a new omap compatible and another moved the IDs to a header which created a conflict: moving the new ID as well in the header fixed it.] Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
