Revert: ARM: SAMSUNG: Add naming of s3c64xx-spi devices

This reverts commit baa526f45d3f096a1cd9f14b668203a03bbab6f9, which is
commit 308b3afb97dc342e9c4f958d8b4c459ae0e22bd7 upstream.

To quote Colin Cross:
	This patch breaks Exynos5 spi on 3.4.17.  The patch with the bug
	that this patch was supposed to address went in to 3.6 and not
	3.4, so this patch causes a driver name mismatch when applied to
	3.4.
