mtd: spi-nor: Create macros to define chip IDs and geometries

The INFO() macro defines an ID array and a couple of geometry
properties. Right now all its lines are duplicated twice because of the
INFO6() macro (for extended IDs) and soon as well we will need to add a
geometry parameter to include the number of banks.

In order to limit the code duplication, let's create a number of
intermediate macros which will facilitate defining high-level INFOX()
macros.

There is no functional change.
