The drm_display_mode is a bit difficult one to use (we need hfp, hbp,
... instead of hsync_start, hsync_end, ...) and understand (when to use
crtc_* fields).
To simplify the code, use struct videomode internally which cleans up
the code. If in the future we want to use crtc_* fields in some code

LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().
Always try to set the largest possible BAR size
