On the Pro 7 and Laptop 3, intel_lpss_pci fails to probe and thus keeps
the system from booting. Add a patch to fix this.
Note: The added patch is on it's way upstream.

This commit will update suspend.patch for 4.19
Backported these two patches:
- torvalds/linux@4eaefe8c62
(nvme-pci: Allow PCI bus-level PM to be used if ASPM is disabled)
- torvalds/linux@accd2dd72c
(PCI/ASPM: Add pcie_aspm_enabled())
on top of these patches that are already backported by commit
qzed/linux-surface@e8a3d85b22
(Update NVMe part of suspend.patch):
- torvalds/linux@d916b1be94
(nvme-pci: use host managed power state for suspend)
- torvalds/linux@1a87ee657c
(nvme: export get and set features)
- torvalds/linux@d6135c3a1e
(nvme-pci: Sync queues on reset)
Tested and confirmed that suspend is working on Surface Book 1 with
THNSN5512GPU7 TOSHIBA NVMe SSD which has issue resuming from suspend
with PCI bus-level PM.

The newer surface devices Pro 4 and up do not define _PRW to specify
which GPE interrupt belongs to the lid. Thus they may not be marked as
wake-up sources automatically, so we have to do this manually.
