Ioana Ciornei July 7, 2022, 9:14 a.m. UTC 
Convert the sff,sfp.txt bindings to the DT schema format.
Also add the new path to the list of maintained files.

Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com>
---
Changes in v2:
 - used the -gpios suffix
 - restricted the use of some gpios if the compatible is sff,sff

Changes in v3:
 - moved the -gpios properties to be under properties and not
   pattern properties.
