arm64: smp: Tidy up cpuinfo init and cpufeature updates

Populating the 'cpuinfo_arm64' structure during CPU bringup and
subsequently checking/updating cpufeature structures is slightly
convoluted and differs unnecessarily between the boot CPU and secondary
CPUs.

Rework the code so that cpuinfo_store_cpu() is used to populate the
'cpuinfo_arm64' structure for each CPU, with secondary CPUs then calling
update_cpu_features() to update the global view of the available
features. This allows us to internalise init_cpu_features() and the
'boot_cpu_data' in cpufeature.c and paves the way for parallelising the
ID register probing during bring-up of secondary CPUs.
