Nuno Sa c83ccdc958 counter: fix privdata alignment ...

Aligning to the L1 cache does not guarantee the same alignment as
kmallocing an object [1]. Furthermore, in some platforms, that
alignment is not sufficient for DMA safety (in case someone wants
to have a DMA safe buffer in privdata) [2].

Sometime ago, we had the same fixes in IIO.
