Ilpo Järvinen db92e3fef5 drm/amdgpu: Remove driver side BAR release before resize
PCI core handles releasing device's resources and their rollback in case of
failure of a BAR resizing operation. Releasing resource prior to calling
pci_resize_resource() prevents PCI core from restoring the BARs as they
were.

Remove driver-side release of BARs from the amdgpu driver.

Also remove the driver initiated assignment as pci_resize_resource() should
try to assign as much as possible. If the driver side call manages to get
more required resources assigned in some scenario, such a problem should be
fixed inside pci_resize_resource() instead.
