ARM: Spectre-BHB: provide empty stub for non-config
commit 68453767131a5deec1e8f9ac92a9042f929e585d upstream.
When CONFIG_GENERIC_CPU_VULNERABILITIES is not set, references
to spectre_v2_update_state() cause a build error, so provide an
empty stub for that function when the Kconfig option is not set.
Fixes this build error:
arm-linux-gnueabi-ld: arch/arm/mm/proc-v7-bugs.o: in function `cpu_v7_bugs_init':
proc-v7-bugs.c:(.text+0x52): undefined reference to `spectre_v2_update_state'
arm-linux-gnueabi-ld: proc-v7-bugs.c:(.text+0x82): undefined reference to `spectre_v2_update_state'
Fixes: b9baf5c8c5c3 ("ARM: Spectre-BHB workaround")
