[PATCH 29/37] powerpc: mpc5121_ads_cpld: remove use of NO_IRQ_IGNORE

[Milton Miller]

As NO_IRQ_IGNORE is only used between the static function cpld_pic_get_irq
and its caller cpld_pic_cascade, and cpld_pic_cascade only uses it to
suppress calling handle_generic_irq, we can change these uses to NO_IRQ
and remove the extra tests and pathlength in cpld_pic_cascade.
