This adds routines for early setup for radix. We use device tree property "ibm,processor-radix-AP-encodings" to find supported page sizes. If we don't find the above we consider 64K and 4K as supported page sizes. We do map vmemap using 2M page size if we can. The linear mapping is done such that we use required page size for that range. For example memory of 3.5G is mapped such that we use 1G mapping till 3G range and use 2M mapping for the rest.
