arm64: Fix __cpu_logical_map undefined issue
The __cpu_logical_map undefined issue occued when the new
tegra194-cpufreq drvier building as a module.
ERROR: modpost: "__cpu_logical_map" [drivers/cpufreq/tegra194-cpufreq.ko] undefined!
The driver using cpu_logical_map() macro which will expand to
__cpu_logical_map, we can't access it in a drvier. Let's turn
cpu_logical_map() into a C wrapper and export it to fix the
build issue.
Also create a function set_cpu_logical_map(cpu, hwid) when assign
a value to cpu_logical_map(cpu).
