drm/amdgpu: disable BAR resize on Dell G5 SE

Browse source

commit 099bffc7ca 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
