board_inspector: fix scope opening in the AML parser

Browse Source 
According to section 19 of ACPI spec 6.4, the following clauses open name
scopes (in addition to the Scope clauses).

  - Function
  - Device
  - Method
  - Power Resource
  - Thermal Zone

The current AML parser only opens a scope when parsing DefMethod and
DefDevice, however. This patch fixes the AML parsing by opening a scope on
visiting a DefPowerRes or DefThermalZone clause.

Note: Functions in ASL are equivalent to Methods at AML level.
