[POWERPC] Fix ucc_geth of_device discovery on mpc832x
mpc832x, as in mpc8360, needs to explicitly find and create the platform device for ucc_geth in 2.6.19. This code will likely be readapted to Benh's new of_ methods for 2.6.20. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
