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.
