arm64: head: Move early kernel mapping routines into C code
The asm version of the kernel mapping code works fine for creating a
coarse grained identity map, but for mapping the kernel down to its
exact boundaries with the right attributes, it is not suitable. This is
why we create a preliminary RWX kernel mapping first, and then rebuild
it from scratch later on.
So let's reimplement this in C, in a way that will make it unnecessary
to create the kernel page tables yet another time in paging_init().
