[PATCH 4/9] mtd: spi-nor: remove unused set_quad_mode() function

[Cyrille Pitchen <cyrille.pitchen@atmel.com>]

The set_quad_mode() function is no longer used, so we remove it.

This patch is not squashed into the previous patch on purpose for
readiness issue and to ease the review process of the whole series.
