Use { } instead of memset() to zero-initialize stack memory to simplify
the code.

[ Upstream commit a4135386fa49c2a170b89296da12c4a3be2089d9 ]
The driver code is full of intXX_t and uintXX_t types which is
not the pattern we use in the IIO subsystem. Switch the driver
to use kernel internal types for that. No functional changes.
