tcx: use standard fields for framebuffer physical address and length 

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.
