ACPICA: Remove global option to serialize all control methods.
According to the reports, the "acpi_serialize" mechanism is broken as: A. The parallel method calls can still happen when the interpreter lock is released under the following conditions: 1. External callbacks are invoked, for example, by the region handlers, the exception handlers, etc.; 2. Module level execution is performed when Load/LoadTable opcodes are executed, and 3. The _REG control methods are invoked to complete the region registrations. B. For the following situations, the interpreter lock need to be released even for a serialized method while currently, the lock-releasing operation is marked as a no-op by acpi_ex_relinquish/reacquire_interpreter() when this mechanism is enabled: 1. Wait opcode is executed, 2. Acquire opcode is executed, and 3. Sleep opcode is executed. This patch removes this mechanism and the internal acpi_ex_relinquish/reacquire_interpreter() APIs. Lv Zheng.
