lib: Use vmalloc.h for setup_mmu definition

There is no good reason to put setup_vm in libcflat.h when it's
defined in vmalloc.h.

s390x: Introduce symbol for lowcore and use it

This gets rid of bunch of pointers pointing to the lowcore used in
various places and replaces it with a unified way of addressing the
lowcore.
The new symbol is not a pointer. While this will lead to worse code
generation (cannot use register 0 for addressing), that should not
matter too much for kvm unit tests.
Since the lowcore is located per definition at address 0, the symbol is
defined via the linker scripts.
The symbol also will be used to create pointers that the compiler cannot
warn about as being outside the bounds of an array.

s390x: mvpg: simple test

A simple unit test for the MVPG instruction.

The timeout is set to 10 seconds because the test should complete in a
fraction of a second even on busy machines. If the test is run in VSIE
and the host of the host is not handling MVPG properly, the test will
probably hang.

Testing MVPG behaviour in VSIE is the main motivation for this test.

Anything related to storage keys is not tested.
