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();

Applied to pci/misc for v5.10, thanks!

We could put it in v5.9, but a912a7584ec3 was merged for v4.16, so apparently this has been broken for a long time.

Found in linux-next, but applies to/exists in mainline also.

v2:

• add Reviewed-by: and Acked-by: tags
• drop alternatives
