[PATCH 7/7] PCI,ACPI: remove obsolete _OSC capability support functions

[Andrew Patterson]

PCI, ACPI: 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 they are removed.
