Patches for S3C64XX SPI controller driver

[Jassi Brar]

Hello,

 In subsequent mails, I am going to submit new SPI driver
for the S3C64xx Samsung SoCs.

 The driver has been tested with 9pin MMC card slot soldered
to pins of SPI-1 port on the SMDK6410.
Since that is not a standard h/w configuration of SMDK, the patch
to enable SPI-1 controller for MMC_SPI in machine init code,
is not being submitted.

Regards.
