Add support for HP Jornada flashrom boards

This patch adds support for the HP Jornada flashboards
that were made in 2008. Older flashroms should work if
memory registers are adjusted.

Signed-off-by: Kristoffer Ericson <kristoffer.ericson@gmail.com>

Adpted for TEXT_BASE -> CONFIG_SYS_TEXT_BASE rename.
Removed now redundant board/jornada/config.mk file.
Removed unused empty jornada_init() function to silence
"jornada.c:35: warning: 'jornada_init' defined but not used"
