[PATCH] drm/panic: Fix panic logo alignment

[Dileep Sankhla]

Display the panic logo at the top center of the screen when
drm_panic_type is set to DRM_PANIC_TYPE_USER to keep the layout
properly aligned.

Hi,

I think this is more a preference, than a fix.
At boot the logo is at the top left corner, and I choose to let it at 
the same place.
Additionally, on low resolution (like 800x600) the logo has less chance 
to overlap the text, so the user is more likely to see it.

Best regards,
