[PATCH 01/43] drm/fbdev-generic: Do not set physical framebuffer address

[Thomas Zimmermann]

Framebuffer memory is allocated via vmalloc() 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.
