Subject: [PATCH mmotm] x86/numa: fix build when CONFIG_ACPI is not set

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

Fix build errors when CONFIG_ACPI is not set/enabled by adding
<acpi/acpi_numa.h> in the #else (!CONFIG_ACPI) block.

../arch/x86/mm/numa.c: In function ‘numa_setup’:
../arch/x86/mm/numa.c:43:3: error: implicit declaration of function ‘disable_srat’; did you mean ‘disable_irq’? [-Werror=implicit-function-declaration]
   disable_srat();
   ^~~~~~~~~~~~
../arch/x86/mm/numa.c:45:3: error: implicit declaration of function ‘disable_hmat’; did you mean ‘disable_dma’? [-Werror=implicit-function-declaration]
   disable_hmat();
   ^~~~~~~~~~~~
