drm/amdgpu: disable BAR resize on Dell G5 SE
commit 099bffc7cadff40bfab1517c3461c53a7a38a0d7 upstream.
There was a quirk added to add a workaround for a Sapphire
RX 5600 XT Pulse that didn't allow BAR resizing. However,
the quirk caused a regression with runtime pm on Dell laptops
using those chips, rather than narrowing the scope of the
resizing quirk, add a quirk to prevent amdgpu from resizing
the BAR on those Dell platforms unless runtime pm is disabled.
v2: update commit message, add runpm check
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/1707
Fixes: 907830b0fc9e ("PCI: Add a REBAR size quirk for Sapphire RX 5600 XT Pulse")
