This patch enables the existing S3C64XX series SPI driver for S5P64X0
and removed dependency on EXPERIMENTAL because we don't need it now.

Changes since v1:
- Removed dependency on EXPERIMENTAL
Hi David and Grant,
I missed that send to you when I have got this via Linux Samsung SoC mailing list.
Hmm...I know, it's 38 merge winodw...so I'm not sure can be handled now.
Anyway if any problems, please let me know.
Thanks and Happy New year :)
Best regards,
Kgene.

Since SoCs newer than S3C64xx use different DMAC, it would be
more efficient to do
select S3C64XX_DMA if ARCH_S3C64XX
otherwise we would have to add lots of !ARCH_S5Pxxx as more SoCs
are enabled.

Yes, you're right.
Will fix it soon.
Thanks.
