Subject: [PATCH] misc/at25, dt: support probing at25 SPI EEPROM from DT

From: Jan Luebbe <jlu@...gutronix.de>

The commit d6ae0d578d24303941c1424b049d2cae28277666 introduced devicetree
binding documentation for this driver, but the driver itself does not yet
support the documented compatible entry. Fix this by adding the documented
entry to the driver.
