arm: Use ARCH_IRQ_INIT_FLAGS
The core code now initializes the requested number of interrupts and
sets the flags in irq_desc.status which are requested by the
architecture via ARCH_IRQ_INIT_FLAGS.
Add ARCH_IRQ_INIT_FLAGS and remove the loop which sets those flags
after the irq descriptors are allocated.
[ This patch should have been in the original irq rework and got
dropped accidentaly ]
