mtd: spi-nor: introduce (temporary) INFO0()

The id will be converted to an own structure. To differentiate between
flashes with and without IDs, introduce a temporary macro INFO0() and
convert all flashes with no ID to use it. The difference between INFO0()
and INFOx() is that the former, doesn't have a pointer to the id
structure. Something which isn't possible to do within the INFOx()
macro.
After the flash_info conversion, that macro will be removed along with
all the other INFOx() macros.
