[PATCH RESEND V3 5/5] spi: s3c64xx: Added support for exynos5440 spi

[Girish K S]

From: Girish K S <girishks2000 at gmail.com>

This patch adds support for the exynos5440 spi controller.
The integration of the spi IP in exynos5440 is different from
other SoC's. The I/O pins are no more configured via gpio, they
have dedicated pins.
