x86/efi/mixed: Set up 1:1 mapping of lower 4GiB in the stub
In preparation for dropping the dependency on startup_32 entirely in the
next patch, add the code that sets up the 1:1 mapping of the lower 4 GiB
of system RAM to the mixed mode stub.
The reload of CR3 after the long mode switch will be removed in a
subsequent patch, when it is no longer needed.
