tools/power/x86/intel-speed-select: Fix the condition to check multi die system

Even when there is no die exported by CPUID leaf 0x1F, the kernel version
after 6.9 will show non zero die_id in the sysfs. In that case maximum
die_id can still match maximum power domain ID. So the condition to check
if the power domain ID is same a die_id to prevent duplicate display
doesn't hold true.

The better condition is to check if the maximum die_id is more than the
maximum package_id. If the die_id is exposed by CPUID leaf 0x1F, the
maximum die_id will be more than maximum package_id.

With this change tracking of max_punit_id is not used, so remove storing
max_punit_id.
