ARM: fix building NOMMU ARMv4/v5 kernels
The removal of the old-style irq entry broke obscure NOMMU
configurations on machines that have an MMU:
ld.lld: error: undefined symbol: generic_handle_arch_irq
referenced by kernel/entry-armv.o:(__irq_svc) in archive arch/arm/built-in.a
A follow-up patch to convert nvic to the generic_handle_arch_irq()
could have fixed this by removing the Kconfig conditional, but did
it differently.
Change the Kconfig logic so ARM machines now unconditionally
enable the feature.
I have also submitted a patch to remove support for the configurations
that broke, but fixing the regression first is a trivial and correct
change.
