ACPI / EC: Cleanup logging/debugging splitter support.
This patch refines logging/debugging splitter support so that when DEBUG is disabled, splitters won't be visible in the kernel logs while they are still available for developers when DEBUG is enabled. This patch also refines the splitters to mark the following handling process boundaries: +++++: boundary of driver starting/stopping boundary of IRQ storming =====: boundary of transaction advancement *****: boundary of EC command boundary of EC query #####: boundary of EC _Qxx evaluation The following 2 log entries are originally logged using pr_info() in order to be used as the boot/suspend/resume log entries for the EC device, this patch also restores them to pr_info() logging level: ACPI : EC: EC started ACPI : EC: EC stopped In this patch, one log entry around "Polling quirk" is converted into ec_dbg_raw() which doesn't contain the boundary marker.
