[PATCH] ArmPkg: fix compilation error in ArmDmaLib

[Leif Lindholm <leif.lindholm@linaro.org>]

Commit 0a99a65d2c8a ("fix incorrect device address of double buffer")
retained an explicit cast on the variable "Buffer" which became
incorrect with the other changes, leading to compilation failures
with some toolchains. Drop the cast.

Mike, Andrew - since Ard is on holiday and the fix is trivial,
could either of you give me a Reviewed-by: on this one?
