ACPI/PCI: Change pci_osc_control_set() to query control bits first

Current pci_osc_control_set() evaluates _OSC without query for control
bits, unless __pci_osc_support_set() is called beforehand. But as
strongly recommended in PCI firmware specification, it should query
control bits first.

This patch changes pci_osc_control_set() to query control bits first
even if __pci_osc_support_set() is not called beforehand.
