[PATCH v1 2/3] x86/platform/intel-mid: Move PCI initialization to arch_init()

From: Andy Shevchenko
Date: Wed Jan 17 2018 - 12:34:46 EST


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.
