Convert the xtensa architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for xtensa this is primarily a matter of moving code.
This has only been build-tested, feedback from architecture maintainers
is welcome.

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

This header file is used by three archs. It could be used by all of them
since relocation is a common function. Move it into a generic file.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>. Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

The 'xtfpga' board is actually a set of FPGA evaluation boards that
can be configured to run an Xtensa processor.
- Avnet Xilinx LX60
- Avnet Xilinx LX110
- Avnet Xilinx LX200
- Xilinx ML605
- Xilinx KC705
These boards share the same components (open-ethernet, ns16550 serial,
lcd display, flash, etc.).
