Subject: [PATCH 06/10] platform/x86: ISST: Shorten the assignments for power_domain_info

Instead of long lines for assignment to tpmi_sst->power_domain_info, use
a local variable pd_info and assign later. Also move the assignment
of number of resources after the assignment of pd_info.

No functional change is expected.
