Framebuffer memory is allocated via vzalloc() from non-contiguous physical pages. The physical framebuffer start address is therefore meaningless. Do not set it.
The value is not used within the kernel and only exported to userspace on dedicated ARM configs. No functional change is expected.
v2: - refer to vzalloc() in commit message (Javier)
