video: tegra: host: register nvhost master device in board-xxx-panel.c
- the suspend order of devices is governed by the order
in which devices are registered
- this commit ensures that nvhost master is registered before
any of the graphics devices
- previously this was done in rootfs_init call which is
later than arch_init calls of board-xxx-panel.c
- this caused tegra-dc device to be registered *before* nvhost
master device. as a result it was suspended *later* than nvhost
master device. this is a clear violation of dependency rule
for nvhost. this caused suspend-resume to fail for L4T
- this worked on android as it has CONFIG early suspend enabled
while it failed for L4T which doesn't have CONFIG early suspend
enabled
