topology/sysfs: Hide PPIN on systems that do not support it.
Systems that do not support a Protected Processor Identification Number
currently report:
# cat /sys/devices/system/cpu/cpu0/topology/ppin
0x0
which is confusing/wrong.
Add a ".is_visible" function to suppress inclusion of the ppin file.
Fixes: ab28e944197f ("topology/sysfs: Add PPIN in sysfs under cpu topology")
