arm64: sysreg: Drag linux/kconfig.h to work around vdso build issue
Broonie reports that fed55f49fad18 ("arm64: errata: Work around
AmpereOne's erratum AC04_CPU_23") breaks one of the vdso selftests
(vdso_test_chacha) as it indirectly drags asm/sysreg.h.
It is rather unfortunate (and worrying) that userspace gets built
with non-UAPI headers. In any case, paper over the issue by dragging
linux/kconfig.h in asm/sysreg.h. It is the right thing to do, at
least from the kernel perspective.
