[PATCH v3 1/3] spi: move `cs_change_delay` backwards compat logic outside switch

From: Alexandru Ardelean
Date: Mon Sep 16 2019 - 03:10:50 EST


The `cs_change_delay` backwards compatibility value could be moved outside
of the switch statement.
The only reason to do it, is to make the next patches easier to diff.
