[PATCH] PCI: vgaarb: Remove stale "not implemented" notes from docs

["Christian Melendez Nuñez" <chrismelnu@gmail.com>]

The vgaarb kerneldoc and Documentation/gpu/vgaarbiter.rst both
describe "unlock all" and "target default" as "(TODO: not
implemented yet)". Both are actually implemented already:

- "unlock all" is handled in vga_arb_write() via the "all"
  strncmp branch, which releases both VGA_RSRC_LEGACY_IO and
  VGA_RSRC_LEGACY_MEM.
- "target default" is handled in the same function via the
  "default" strncmp branch, which resolves the target to
  vga_default_device().

Drop the stale disclaimers so the documentation matches actual
behavior.

This is my first submission to the kernel; happy to take any
feedback on the patch itself or how I should be doing this.
