gma: Make cleaning the hardware state optional
In Initialize(), the state of the graphics hardware is reset to a
known state (i.e. everything is turned off first). That's unnecessary
in the coreboot case where we just came out of reset. Thus, make the
state cleaning optional with a `Clean_State` parameter that defaults
to `False`.
