ACPI / PM: Use ACPI_STATE_D3_COLD instead of ACPI_STATE_D3 everywhere
Browse files Browse the repository at this point in the history
There are several places in the tree where ACPI_STATE_D3 is used
instead of ACPI_STATE_D3_COLD which should be used instead for
clarity.  Modify them all to use ACPI_STATE_D3_COLD as appropriate.

[The definition of ACPI_STATE_D3 itself cannot go away at this point
 as it is part of ACPICA.]
