When parsing an AML object representing a host bridge, the current board
inspector may encounter the following issues:
1. The host DSDT may contain multiple host bridge instances, with some of
them not being present. In this case the _BBN of these instances may
evaluate to the same value that coincide with the bus assigned to an
existing host bridge, leading to multiple PCI bus nodes with the same
bus number and thus confusion in later information extraction phases.
2. Methods of a host bridge may refer to the PCI configuration space of
itself (which is typically Device 0, Function 0 under that
bus). However, such objects may not have an _ADR object as the bus
number is encoded by the _BBN object instead.
This patch fixes the issues above.

board_parser.py will collect all board related info and then generate a board info file for acrn-config host tool usage. usage: python3 cli.py <board_name> [--out board_info_file] board_name : the name of board that run ACRN hypervisor, like apl-up2/nuc7i7dnb. It will be used as name of the board configurations folder which created by acrn-config host tool. board_info_file : (optional) the name of board info file. if it is not specified, a name of <board_name>.xml will be generated under the current working directory by default. Please run this script under native Linux environment with root privilege. OS requirement: Release: Ubuntu 18.04+ Tools: cpuid, rdmsr, lspci, lxml, dmidecode (optional) kernel cmdline: "idle=nomwait intel_idle.max_cstate=0 intel_pstate=disable"
