topology/sysfs: Add format parameter to macro defining "show" functions for proc
All the simple (non-mask and non-list files in
/sys/devices/system/cpu/cpu0/topology/ are currently printed as decimal
integers.
Refactor the macro that generates the "show" functions to take a format
parameter to allow future files to display in other formats.
No functional change.
