Staging: cx23885: fix include of altera.h

The cx23885 driver was including staging/altera.h, but that file has
moved back into the driver directory.

Why a non-staging driver was including a staging driver is beyond me,
but this fixes the build so everything is happy for now.

For the record, it's not ok for a non-staging driver to depend on a
staging one, as that implies that the non-staging one should also be in
the staging tree if that's needed.
