[ARM] 5255/1: Update jornada ssp to remove build errors/warnings
* Adds ssp functions into header so we don't get "implicit declaration" error at builtime. * Converts jornada_ssp_start/end functions into voids with proper declarations (to avoid "prototype..." warning). * Sorts include files in alphabetical order * Minor comment changes Signed-off-by: Kristoffer Ericson <Kristoffer.Ericson@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
