[PATCH] cxl: replace loop with for_each_child_of_node(), remove unneeded of_node_put()

Rewrite the cxl_guest_init_afu() loop in cxl_of_probe() to use for_each_child_of_node() rather than a hand-coded for loop. Remove the useless of_node_put(afu_np) call after the loop, where it's guaranteed that afu_np == NULL. Reported-by: SF Markus Elfring

[PATCH v4] powerpc/mm: Do hash device tree scanning earlier

Currently MMU initialisation (early_init_mmu()) consists of a mixture of scanning the device tree, setting MMU feature bits, and then also doing actual initialisation of MMU data structures. We'd like to decouple the setting of the MMU features from the actual setup. So split out the device tree
