gma: Correct Global annotation for Initialize()

On G45, we use the private PCI device `Dev` during
Power_And_Clocks.Initialize(). As its `Dev.PCI_State`
is not directly visible in the sub-package, it is
assumed that the whole, abstract `Device_State` can
be altered. This includes `Registers.GTT_State`.

Correcting the `Globals` aspect for G45 makes it
excessive for other platforms, hence we need the
same forest of additional justifications and anno-
tations as we have for Power_Up_VGA().
