Documentation/gpu: remove completed drm_simple_encoder_init() todo

All drm_simple_encoder_init() users have been removed, so drop the
completed todo item.

[Severity: Low]
Are there still remaining users of drm_simple_encoder_init() in the tree?

Looking at the gma500 driver, it appears there are several unconverted calls
remaining, such as in drivers/gpu/drm/gma500/cdv_intel_crt.c:

cdv_intel_crt_init() {
    ...
    ret = drm_simple_encoder_init(dev, encoder, DRM_MODE_ENCODER_DAC);
    ...
}

There also seem to be similar calls in cdv_intel_dp.c, cdv_intel_hdmi.c,
cdv_intel_lvds.c, oaktrail_hdmi.c, oaktrail_lvds.c, and psb_intel_lvds.c.

Will this cause a build failure when compiling with CONFIG_DRM_GMA500 if the
underlying function is removed before these are converted?
