ARM: OMAP2+: onenand: connected soc info in pdata

Browse Source 
onenand driver needs to know whether soc is falling under
34xx family to properly handle onenand. But driver is not
supposed to do cpu_is_* check, hence educate platform data
with this information. Driver can make use of it to avoid
cpu_is_* check.
