Update v4.19 patches

Browse source 
Changes:
  SAM:
    - Add support for Surface Book 3 in Surface HPS driver. The dGPU of
      the Surface Book 3 can now be turned on and off via the same
      mechanism already being used by the Surface Book 2.
    - Add SID devices for Surface Pro 6 with MSHW0111 ID.
    - Complete restructure of Surface Serial Hub driver internals. The
      old synchronous communication core has been replaced by a
      completely asynchronous implementation.
    - Misc. code improvements and clean-up.
