Lv Zheng df45db6177 ACPI / EC: Add PM operations for suspend/resume noirq stage ... It is reported that on some platforms, resume speed is not fast. The cause is: in noirq stage, EC driver is working in polling mode, and each state machine advancement requires a context switch. The context switch is not necessary to the EC driver's polling mode. This patch implements PM hooks to automatically switch the driver to/from the busy polling mode to eliminate the overhead caused by the context switch. This finally contributes to the tuning result: acpi_pm_finish() execution time is improved from 192ms to 6ms.
