ACPI: Fix build failure when CONFIG_NLS is set to 'n'

Browse source 
Observing link failure as follows when CONFIG_ACPI is set but
both CONFIG_NLS and CONFIG_PCI are no set:

drivers/acpi/device_sysfs.o: In function `description_show':
device_sysfs.c:(.text+0x48a): undefined reference to `utf16s_to_utf8s'

This issue was previously addressed implicitly by commit 8a226e00ee
(PCI: pci-label: Fix build failure when CONFIG_NLS is set to 'm' by
allmodconfig) causing PCI_LABEL to be selected when ACPI was set
which caused NLS to be selected too in that case.

However, after commit 5d32a66541 (PCI/ACPI: Allow ACPI to be built
without CONFIG_PCI set) it is possible to build ACPI support without
PCI, so make ACPI select NLS directly to cover that case.

Fixes: 5d32a66541 (PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set)
