drm/amdkfd: avoid svm dump when dynamic debug disabled
Set dynamic_svm_range_dump macro to avoid iterating over SVM lists
from svm_range_debug_dump when dynamic debug is disabled. Otherwise,
it could drop performance, specially with big number of SVM ranges.
Make sure both svm_range_set_attr and svm_range_debug_dump functions
are dynamically enabled to print svm_range_debug_dump debug traces.
