arm64: Mark call_smc_arch_workaround_1 as __maybe_unused 

When building allnoconfig:

arch/arm64/kernel/cpu_errata.c:174:13: warning: unused function
'call_smc_arch_workaround_1' [-Wunused-function]
static void call_smc_arch_workaround_1(void)
            ^
1 warning generated.

Follow arch/arm and mark this function as __maybe_unused.
