The hardware related pipelines are obviously not available on other
architectures.
As suggested by upstream [0], add a dependency on arm or aarch64 for
RaspberryPi pipeline, to avoid the following build failure with a
powerpc64 toolchain since commit c09f126f57 (package/libcamera: bump
to version e355ca0087cd93ef80f74c61018e9e9228a93313):

Additionally, as Kieran puts it:
I'd go further and filter the IPU3 on only x86 for instance, and the
RKISP on (arm||aarch64).
So be it.
