mtd: spi-nor: remove unused read_xfer/write_xfer hooks
Based on the Linux v4.3 patch: commit 79c452adb159dc9abc507ea13faec8d115a78758 Author: Cyrille Pitchen <cyrille.pitchen@atmel.com> AuthorDate: Fri Sep 18 17:49:25 2015 +0200 Commit: Brian Norris <computersforpeace@gmail.com> CommitDate: Mon Sep 21 16:49:52 2015 -0700 mtd: spi-nor: remove unused read_xfer/write_xfer hooks struct spi_nor_xfer_cfg and read_xfer/write_xfer hooks were never used by any driver. Do some cleanup by removing them.
