ACPI: Eliminate us to pm ticks conversion in common path
acpi_enter_[simple|bm] routines does us to pm tick conversion on every idle wakeup and the value is only used in /proc/acpi display. We can store the time in us and convert it into pm ticks before printing instead and avoid the conversion in the common path.
