The commit e254b584dbc0 ("drm/ssd130x: Remove hardcoded bits-per-pixel in
ssd130x_buf_alloc()") used a pixel format info instead of a hardcoded bpp
to calculate the size of the buffer allocated to store the native pixels.
But that wrongly used the DRM_FORMAT_C1 fourcc pixel format, which is for
color-indexed frame buffer formats. While the ssd103x controllers don't
support different single-channel colors nor a Color Lookup Table (CLUT).
Both formats use eight pixels/byte, so in practice there is no functional
changes in this patch. But still the correct pixel format should be used.
