[PATCH] cxl: Ensure PSL interrupt is configured for contexts with no AFU IRQs

From: Ian Munsie In the cxl kernel API, it is possible to create a context and start it without allocating any interrupts. Since we assign or allocate the PSL interrupt when allocating AFU interrupts this will lead to a situation where we start the context with no means to take any faults. The u
