rS298484: Optionally return the output capabilities list from _OSC.
Summary

Optionally return the output capabilities list from _OSC.

Both of the callers were expecting the input cap_set to be modified.
This fixes them to request cap_set to be updated with the returned buffer.

Test Plan
  • booted on my laptop (has both PCI and CPU _OSC methods)
  • I added extra debugging to print out the _OSC status, returned buffer length and first word.
