PCI/ACPI: Validate acpi_pci_set_power_state() parameter
Previously acpi_pci_set_power_state() assumed the requested power state was
valid (PCI_D0 ... PCI_D3cold). If a caller supplied something else, we
could index outside the state_conv[] array and pass junk to
acpi_device_set_power().
Validate the pci_power_t parameter and return -EINVAL if it's invalid.
