mtd: nand: add onfi_* stubs in case ONFI_DETECTION is disabled

Add stubs to the header in case CONFIG_SYS_NAND_ONFI_DETECTION is
disabled.  This is much easier than adding around #ifdef to the
caller side.

Also, I removed the #ifdef around onfi_params.  In Linux, onfi_params
and jedec_params are unified as union.  It will be the right thing
to do.
