ACPICA: Debugger: Fix runtime stub issues of ACPI_DEBUGGER_EXEC using different stub mechanism
ACPICA commit 11522d6b894054fc4d62dd4f9863ec151296b386 The ACPI_DEBUGGER_EXEC is a problem now when the debugger code is compiled but runtime disabled. They actually will get executed in this situation. Although such executions are harmless if we can correctly make acpi_db_single_step() a runtime stub, users may still do not want to see the debugger print messages logged into OSPMs' kernel logs when a debugger driver is not loaded to enable the debugger during runtime. This patch fixes this issue by introducing new stub mechanism instead of ACPI_DEBUGGER_EXEC. Lv Zheng.
