[PATCH v2] drm/panthor: fix immortalis condition

[Erik Faye-Lund]

Exactly 10 cores is also valid for an Immortalis configuration,
according to the public documentation:

https://support.arm.com/compute-ip/immortalis-g715

So let's report this G715 with 10 cores as Immortalis as well, as long
as it supports the ray-intersection feature. This matches what we do for
more recent GPUs as well.

I'll push this to drm-misc-fixes.
