spi: spi_bfin: update handling of delay-after-deselect
Move cs_chg_udelay handling (specific to this driver) to cs_deactive(), fixing a bug when some SPI LCD driver needs delay after cs_deactive. Fix bug reported by Cameron Barfield <cbarfield@cyberdata.net> https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=23630&feedback=Message%20replied.
