soc/amd/*/acpi/mmio.asl,sb_fch.asl: hide AAHB device
Don't set bit 2 in _STA in order for Windows not to show a warning about
an unknown device in the device manager for this device. Since the _STA
object just returns a constant, a name definition can be used instead of
a method definition.
TEST=The unknown device with device instance path ACPI\AAHB0000\0
disappeared from the device manager in Windows 10 build 19045 on a
Mandolin board with a Picasso APU.
Just shutting down and then booting it again won't clear some internal
state in Windows, so a reboot is needed instead for the change to become
visible.
