Use irq_data access helper to access irq_data-msi_desc, so we could
move msi_desc from struct irq_data into struct irq_common_data later.

These look OK.
Though I would point out we already have 16 irq_foo_get_bar() accessors?!
Hi Michael,
Thanks for review. We are trying to solve some issues introduced
by hierarchy irqdomain/irqchip by splitting irq_data into a common part
(irq_common_data) and per-chip part(irq_data). These accessors are used
to ease the transition and hide implementation details.
Thanks!
Gerry
