Subject: [PATCH 5.8 23/70] x86/PCI: Fix intel_mid_pci.c build error when ACPI is not enabled

From: Randy Dunlap <rdunlap@...radead.org>

commit 035fff1f7aab43e420e0098f0854470a5286fb83 upstream.

Fix build error when CONFIG_ACPI is not set/enabled by adding the header
file <asm/acpi.h> which contains a stub for the function in the build
error.

    ../arch/x86/pci/intel_mid_pci.c: In function ‘intel_mid_pci_init’:
    ../arch/x86/pci/intel_mid_pci.c:303:2: error: implicit declaration of function ‘acpi_noirq_set’; did you mean ‘acpi_irq_get’? [-Werror=implicit-function-declaration]
      acpi_noirq_set();

Fixes: a912a7584ec3 ("x86/platform/intel-mid: Move PCI initialization to arch_init()")
