platform/x86/intel-uncore-freq: Fix warning in partitioned system
A partitioned system configured with only one package and one compute
die, warning will be generated for duplicate sysfs entry. This typically
occurs during the platform bring-up phase.
Partitioned systems expose dies, equivalent to TPMI compute domains,
through the CPUID. Each partitioned system must contains at least one
compute die per partition, resulting in a minimum of two dies per
package. Hence the function topology_max_dies_per_package() returns at
least two, and the condition "topology_max_dies_per_package() > 1"
prevents the creation of a root domain.
In this case topology_max_dies_per_package() will return 1 and root
domain will be created for partition 0 and a duplicate sysfs warning
for partition 1 as both partitions have same package ID.
To address this also check for non zero partition in addition to
topology_max_dies_per_package() > 1.
