Modernize vga_switcheroo by using a "device link" to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into. Remove thereby obsoleted code and fix a bunch of bugs. Device links were introduced in v4.10. Users might see a small power saving if the discrete GPU is in use and its HDA controller is not, because the HDA controller is now allowed to runtime

Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase
