mb/purism/librem_mini: Hide Linux GPIO LED from Windows 

Hide the Linux gpio-led ACPI device from Windows by setting the device
status (_STA) to 0xB (enabled, hidden) so Windows doesn't show an
unknown device/missing drivers in Device Manger. Linux doesn't care
about the _STA value.

Test: build/boot Windows (10/11) and Linux (PureOS 10) on a Librem Mini
v2, verify LED works under Linux, is ignored under Windows
