Subject: [PATCH] powerpc: chrp: Use of_node_is_type to access device_type

Commit 8ce5f8415753 ("of: Remove struct device_node.type pointer")
removed struct device_node.type pointer, but the conversion to use
of_node_is_type() accessor was missed in chrp_init_IRQ().

Michael, I see you just sent a PR of fixes. I can send this to Linus if 
you prefer.
