ACPI/PCI: remove obsolete _OSC capability support functions 

The acpi_query_osc, __pci_osc_support_set, pci_osc_support_set, and
pcie_osc_support_set functions have been obsoleted in favor of setting
these capabilities during root bridge discovery with
pci_acpi_osc_support.  There are no longer any callers of these
functions, so remove them.
