ACPI: add acpi_get_cpu_uid() stub helper
When ACPI is disabled, x86 Xen support fails to build:
arch/x86/xen/enlighten_hvm.c: In function 'xen_cpu_up_prepare_hvm':
arch/x86/xen/enlighten_hvm.c:165:13: error: implicit declaration of function 'acpi_get_cpu_uid' [-Wimplicit-function-declaration]
165 | if (acpi_get_cpu_uid(cpu, &cpu_uid) == 0)
| ^~~~~~~~~~~~~~~~
Add a trivial stub that can be used in place of the real function.
Fixes: f652d0a4e13c ("ACPI: Centralize acpi_get_cpu_uid() declaration in include/linux/acpi.h")
