2022-04-28PCI/ACPI: add a helper for retrieving _OSC Control DWORDsVishal Verma3-2/+15
During _OSC negotiation, when the 'Control' DWORD is needed from the result buffer after running _OSC, a couple of places performed manual pointer arithmetic to offset into the right spot in the raw buffer. Add a acpi_osc_ctx_get_pci_control() helper to use the #define'd DWORD offsets to fetch the DWORDs needed from @acpi_osc_context, and replace the above instances of the open-coded arithmetic.
