Subject: [PATCH] mtd: spi-nor: macronix: enable dual and quad read for MX25U25635F

From: Parth Pancholi <parth.pancholi@...adex.com>

The MX25U25635F supports dual and quad read operations. Set the
corresponding flags to enable these features in accordance with
the hardware capabilities. This change also enables dual and quad
read operations on the MX25U25645G, which shares the same ID and
has a superset of the functionality provided by the MX25U25635F.
