topology: use bin_attribute to break the size limitation of cpumap ABI
Reading /sys/devices/system/cpu/cpuX/topology/ returns cpu topology.
However, the size of this file is limited to PAGE_SIZE because of
the limitation for sysfs attribute.
This patch moves to use bin_attribute to extend the ABI to be more
than one page so that cpumap bitmask and list won't be potentially
trimmed.
