[ARM] 3764/1: S3C24XX: change type naming to kernel style

Patch from Ben Dooks

The type naming in the s3c24xx dma code is riddled with
typedefs creating _t types, from the code import from 2.4
which is contrary to the current Kernel coding style.

This patch cleans this up, removing the typedefs and
and fixing up the resultant code changes.
