Subject: [PATCH 5/5] ARM i.MX: Remove iram_alloc/free, as they are unused in-tree

Users of the iram_alloc/free API should
convert to the genalloc API instead:

-	virt = iram_alloc(SIZE, &phys);
+	gen_pool_alloc(iram_pool, SIZE);
+	phys = gen_pool_virt_to_phys(iram_pool, virt);
 	/* ... */
-	iram_free(virt, SIZE);
+	gen_pool_free(iram_pool, virt, SIZE);
