So far we were not capturing any HUB interrupt, just core. This could
be a problem if any is fired, as we could enter on an infinite
loop. With this commit we start to capture them. So we split v3d_isr
into core and hub interrupt handling.
As reference we capture the same HUB interrupts that we capture on the
v3d kernel support.
It is worth to note that all those are mostly untested. Now with both
opengl/vulkan driver being stable we were not able to raise those
interrupts.
v2 (Juan feedback):
* Just one V3D_VERSION >= 41 block, more readable
* Assert that the core is 0 at v3d_isr_core (we don't handle
multi-core right now).
