[PATCH 5.7 104/124] Fix build error when CONFIG_ACPI is not set/enabled:

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

[ Upstream commit ee87e1557c42dc9c2da11c38e11b87c311569853 ]

../arch/x86/pci/xen.c: In function ‘pci_xen_init’:
../arch/x86/pci/xen.c:410:2: error: implicit declaration of function 
‘acpi_noirq_set’; did you mean ‘acpi_irq_get’? 
[-Werror=implicit-function-declaration]
  acpi_noirq_set();

Fixes: 88e9ca161c13 ("xen/pci: Use acpi_noirq_set() helper to avoid #ifdef")
