This makes the size of flash 64 bit safe so that we can have flash
devices greater than 4GB. This is especially useful for mambo disks
passed through to Linux.
Fortunately the device tree interface and the linux device driver are
64bit safe so no changes are required there.
Userspace gard and flash tools are also updated to ensure "make check"
still passes.

The ecc 'memcpy' style functions return success or fail in terms of the ECC
enum. This doesn't really make sense, use true or false. As the result the
ecc enum doesn't need to be exposed anymore, which makes more sense, not
clear why it was exposed in the first place.
Convert some of the ecc #defines to static inlines, shouldn't make any
difference but feels safer.
Fix minor stylistic and typo issues.

This patch is twofold.
1. Improves the low level ecc memcpy code to better
specify that we're reading/writing buffers with ecc bytes.
2. Improves/creates the libflash interfaces for ecc.
This patch also includes some tests

libflash should be compilable without the skiboot definitions.

The ecc.h header is used by libflash, so should sit in libflash, to
allow non-skiboot tools to access it.
This change is a simple move of the header file - no changes are made to
the header itself.
