[PATCH]: ACPI: Skip the power state check in power transition

[yakui_zhao <yakui.zhao@intel.com>]

From: Zhao Yakui <yakui.zhao@intel.com>

Skip the power state check in course of power transition by changing the
default value of acpi_power_nocheck to 1. If so, it is unnecessary to add the
boot option of "acpi.power_nocheck=1" or add it into DMI power check table to
skip the power state check.

Of course the power state check still can be enabled by adding the boot option
of "acpi.power_nocheck=0".
