Using board code to enable the MMU is not nice. Do it in generic
code. Since mmu_enable() is now done in mmu_64.c we no longer have
to export it.

Now that we do the initial flat mapping as device memory all addresses
that are not SDRAM are already mapped as device memory, so we can drop
the mapping from the board file.

Instead of #ifdefing the correct pgtable header file to include,
include it where it's needed. Also, move the memory type attributes
into there consumers, namely the mmu.c files.

Currently it's hardcoded for each board which defaultenv version is
used. This is unfortunate since some people like the other defaultenv
version better and may want to select it.
This patch removes the board specific environment path
CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via:
if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC))
defaultenv_append_directory(defaultenv_<board>);
This way we can make sure that the defaultenv-1 board specific bits are
only compiled in when defaultenv-1 is actually in use.
The next step is to make the defaultenv version selection a user visible
choice.

Introduce mach-qemu and add qemu virt64 board which emulates arm64 board.
