MIPS: Octeon: Simplify irq_cpu_on/offline irq chip functions
Make use of the IRQCHIP_ONOFFLINE_ENABLED flag and remove the wrappers. Use irqd_irq_disabled() instead of desc->status, which will go away. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Tested-by: David Daney <ddaney@caviumnetworks.com>
