Subject: [PATCH 16/21] drm/radeon: add quirk to make HP nx6125 laptop resume.

commit 580b4fffbbdc3c899ee1f8189ba321bd60b48840 upstream.

For some reason on resume, executing the BIOS scripts locks up the whole chipset, by avoiding the dynclk table the machine resumes properly and seems to function okay.
