Subject: [ 009/108] ARM: S3C24XX: Add missing DMACH_DT_PROP

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiko Stuebner <heiko@...ech.de>

commit e1267371eacf2cbcf580e41f9e64a986cdaf5c1d upstream.

Commit 2b90807549 (spi: s3c64xx: add device tree support) requires
the DMACH_DT_PROP element in the dma_ch enum. It's not used on non-DT
platforms but has to be present nevertheless.

So mimic the dummy-add of DMACH_DT_PROP on s3c64xx for s3c24xx
machines, to correct the build breakage for the s3c24xx variants
using the s3c64xx-spi-driver.
