meson: Enable simple pipeline handler on all platforms by default

The simple pipeline handler is enabled by default on arm platforms only,
as it used to support arm SoCs only. Now that support for the IPU6 has
been added to the pipeline handler, it should be enabled on x86
platforms as well. Fix it.
