The Exynos 7 arm64 support now allows the S3C64xx SPI driver to be
compiled into an ARM64 kernel, so the cast from the [rt]x_dmach int
variable to a void* in this driver now triggers a warning.
Add a long cast to silence the compiler.

Hi,
this is only compile-tested for arm and arm64. Could someone with
the hardware please confirm that it still works?
Cheers,
Andre.
