v4l2: Enable V4L2 Probes for all platforms
I've started getting email report of issues from users because their m2m drivers aren't detected on PC. The reason is that the v4l2 probes function in the plugin are only included on arm and aarch64 build.
This was added after @tpm request, but I'm not sure base on what. The probe overhead is really small since it skips over all camera that might be connected. For each video devices, for which most PC have a limited number, it will open() ioctl() close(). The ioctl is only querying static information from the driver.
Only if one of these special device is found that there will be extra work, but an effort was made to keep it small.
So I'm suggesting to change the default to true (which is the case in meson build system already). This way, upon next update, these special drivers will be usable by everyone without having to rebuild your distro package. Just looking for yes / no answer here, if no answer in few days I'll assume yes and change this in 1.15 and 1.14.
