drivers/intel/gma: Use libgfxinit Update_Output to turn off graphics
We were using the libgfxinit `Initialize' function with the
`Clean_State' parameter because the more appropriate `Update_Output'
function was not performing all the necessary clean up operations for
the PEIM driver to be successful when libgfxinit was used in romstage.
Thanks to a lot of experiments and some log analysis efforts, we were
able to identify the missing operation and fix the `Update_Output'
function (cf. https://review.coreboot.org/c/libgfxinit/+/72123).
The `initialized' global variable is now unnecessary as we track the
initialization in the Ada code instead.
Since the `Update_Output' function does not return any value, this
patch modifies the `gma_gfxstop' prototype accordingly. This does not
have any impact as the return value was not used anyway.
