From: Krzysztof Helt <krzysztof.h1@xxxxx>
Use standard fields fbinfo.fix.smem_start and fbinfo.fix.smem_len
for physical address and length of framebuffer.
This also fixes output of the 'fbset -i' command - address and length
of the framebuffer are displayed correctly.

I tested this patch on a real hardware (SS20 + TGX card).
