Some more 0.6 fixes

Not sure about the ambiguity fix, tagging the doc to mv! is quite coarse. For reference, the error was:

MethodError:

mv!(
    ::Char,
    ::Float32,
    ::CUSPARSE.CudaSparseMatrixCSR{Float32},
    ::CUDArt.CudaArray{Float32,1},
    ::Float32,
    ::CUDArt.CudaArray{Float32,1},
    ::Char)
is ambiguous. Candidates:

mv!(
    transa::Char,
    alpha::Union{Complex{Float32}, Complex{Float64}, Float32, Float64}
    A::Union{CUSPARSE.CudaSparseMatrixBSR{T}, CUSPARSE.CudaSparseMatrixCSC{T}, CUSPARSE.CudaSparseMatrixCSR{T}, CUSPARSE.CudaSparseMatrixHYB{T}} where T
    X::CUDArt.CudaArray{T,1} where T, beta::Union{Complex{Float32}, Complex{Float64}, Float32, Float64}
    Y::CUDArt.CudaArray{T,1} where T
    index::Char)
in CUSPARSE at /home/tbesard/Projects/Julia-CUDA/CUSPARSE/src/sparse.jl:686

mv!(
    transa::Char,
    alpha::Float32
    A::Union{CUSPARSE.CudaSparseMatrixCSR{Float32}, Hermitian{Float32,CUSPARSE.CudaSparseMatrixCSR{Float32}}, Symmetric{Float32,CUSPARSE.CudaSparseMatrixCSR{Float32}}}
    X::CUDArt.CudaArray{Float32,1}, beta::Float32
    Y::CUDArt.CudaArray{Float32,1}
    index::Char)
in CUSPARSE at /home/tbesard/Projects/Julia-CUDA/CUSPARSE/src/sparse.jl:738

Possible fix, define
  mv!(::Char, ::Float32, ::CUSPARSE.CudaSparseMatrixCSR{Float32}, ::CUDArt.CudaArray{Float32,1}, ::Float32, ::CUDArt.CudaArray{Float32,1}, ::Char)

OK, so the same ambiguity hits with other methods (incl mm!). Will need a proper fix.
