The routines efi_runtime_init32() and efi_runtime_init64() are almost indistinguishable, and the only relevant difference is the offset in the runtime struct from where to obtain the physical address of the SetVirtualAddressMap() routine. However, this address is only used once, when installing the virtual address map that the OS will use to invoke EFI runtime services, and at the time of the call, we will necessarily be running with a 1:1 mapping, and so there is no need to do the map/unmap dance here to retrieve the address. In fact, in the preceding changes to these users, we stopped using the address recorded here entirely. So let's just get rid of all this code since it no longer serves a purpose. While at it, tweak the logic so that we handle unsupported and disable EFI runtime services in the same way, and unmap the EFI memory map in both cases.
