[PATCH] video: offb: Pass actual name in offb_init_palette_hacks

This is a partial revert of commit 5c63e407aaab ("fbdev: Convert to
using %pOFn instead of device_node.name"). This is the minimal work to
get a Mac Mini G4 back to a bootable state. The function
offb_init_palette_hacks would need to handle the case where `name` has
been set to NULL.
