intel/dev: Update hwconfig => max_threads_per_psd for Xe2
One patch from !29706, which @fjdegroo identified as helpful independent from TBIMR (!29706 (comment 2543546)). @zehortigoza reviewed this patch, and @llandwerlin looked at it previously. I'll hold off a bit in case @llandwerlin wants me to an r-b.
