misc: fail to save config_summary.rst while changing board.xml

This patch is to fix the bug which will report while changing board.xml.

The issue was that all data structures were class variables,
Data will be accumulated when calling
main(board_xml, scenario_xml, config_summary).

This patch moved all shared data to instance variables in __init__().
self.io_port = {}
self.io_description = []
self.pci_vuart = {}
self.pci_ivshmem = {}
self.amount_l3_cache = {}
self.service_vm_used_pcpu_list = []
