[PATCH] of/fdt: Clean up early_init_dt_reserve_memory_arch()

[Peter Collingbourne]

As of commit 18250b43f7b6 ("of: fdt: Remove
early_init_dt_reserve_memory_arch() override capability") this is
no longer an arch hook, so rename it to remove the confusing _arch
suffix. Also remove some unnecessary indirection from all but one of
the callers by calling memblock_reserve() directly instead.
