arm64: cpufeature: reorder cpus_have_{const, final}_cap()
In a subsequent patch we'll modify cpus_have_const_cap() to call cpus_have_final_cap(), and hence we need to define cpus_have_final_cap() first. To make subsequent changes easier to follow, this patch reorders the two without making any other changes. There should be no functional change as a result of this patch.
