Subject: [PATCH v2 10/10] ACPI: Replace irqdomain.h include with struct
 declarations

linux/acpi.h includes irqdomain.h which includes of.h. Break the include
chain by replacing the irqdomain include with forward declarations for
struct irq_domain and irq_domain_ops which is sufficient for acpi.h.

of.h also includes mod_devicetable.h which many drivers implicitly
depend on. As acpi.h already includes it, just move it out of the
'#ifdef CONFIG_ACPI'.
