[PATCH v2 2/5] sysinfo: Provide some global/default IDs

[Sean Anderson]

This adds an ID for a board revision. Existing IDs have been moved above
SYSINFO_ID_END to allow for future expansion.

Signed-off-by: Sean Anderson <sean.anderson at seco.com>

Changes in v2:
- Set BOARD_HWVERSION to SYSINFO_ID_REVISION, as they represent the same
  content.
- Use enums instead of defines for sysinfo ids
