uart-render-controller: Use new sysfs paths

The kernel now contains a patch "drm/aspeed: Add sysfs for output
settings" that has been merged to mainline for 5.11. This patch has the
required files under the drm (GPU) device, so the paths have changed.

The openbmc kernel carries this in dev-5.8 as of f43cef68025d. For now
both old and new paths will work, but the old path will be removed in
the future.

(From meta-phosphor rev: 39db01c017971cee5ac2e9db025e3574041e208c)
