[PATCH v5 3/3] mtd: spi-nor: add entry for Macronix mx25l25673g

[Cyrille Pitchen]

The Macronix MX25L25635E and MX25L25673G share the same JEDEC ID, C22019,
with no extended ID to differenciate them at runtime.

However, the 73G supports dedicated 4byte address op code for (Fast) Read,
Page Program and Sectore Erase Operation whereas the 35E doesn't.

So this patch adds a specific entry to support the 73G revision.

For backward compatibility purpose, this new entry is inserted AFTER the
legacy "mx25l25635e" entry so this later entry is still the first one
found hence returned by spi_nor_read_id().

Then using the new entry requires the "mx25l25673g" string to be given
as the 'name' argument of spi_nor_scan().
