x86/platform/intel-mid: Move PCI initialization to arch_init()

ACPI redefines x86_init.pci.init when enabled. Though we still need special
treatment for MID platforms.

Move our specific callback to x86_init.pci.arch_init() and, by calling
acpi_noirq_set(), take back a control over IRQ assignment.
