[RFC Part1 v1 16/18] x86: irq_remapping: Use helpers to access irq_cfg data structure associated with IRQ

[Jiang Liu]

Use helpers to access irq_cfg data structure associated with IRQ,
instead of accessing irq_data->chip_data directly. Later we could
rewrite those helpers to support hierarchy irqdomain.
