misc/at25, dt: support probing at25 SPI EEPROM from DT

The commit 13612b6a2df8daa4d3f9bcdb55b552e5e5fc6688 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.
