[coreboot] build fails when CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT is set

[Iru Cai]

Hi,

I was trying to build coreboot with the latest git code and build failed
when CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT is set. Some of the error message
is:

$ make
    CREATE     build/mainboard/lenovo/x220/cbfs-file.c7KD3B.out (from
src/mainboard/lenovo/x220/cmos.default)

'struct edid' has no member named 'hborder'
  right_border = edid.hborder;
                     ^

After I searched the git log, I found this commit cause the error:
commit 7dbf9c6747ccdfa8b993d3843a22722742957611

edid: Use edid_mode struct to reduce redundancy

This replaces various timing mode parameters parameters with
    an edid_mode struct within the edid struct.

I hope someone will fix the error soon.
