[PATCH v3 08/13] mtd: st_spi_fsm: Update the JEDEC probe to handle extended READIDs

The previous code was based on 3-byte JEDEC IDs, with a possible 2-byte
extension.  However, devices are now emerging that return 6 or more bytes of
READID data and the additional bytes are required to differentiate between
variants or generations of similar devices.

This patch refactors the device table and JEDEC probe code to handle arbitrary
length READIDs, with the standard JEDEC definition now becoming a special case.
Functionally, there should be no change in behaviour.  A subsequent patch will
update the table with extended READIDs where applicable.

BTW, how's that promise going, where you work on adapting this driver to
the spi-nor framework? We've already done some of this same work there.

+#define RDID(...) __VA_ARGS__  /* Dummy macro to protect array argument. */

What? What needs "protected"?
