dmaengine: pxa_dma: fix the maximum requestor line
commit 6bab1c6afdca0371cfa957079b36b78d12dd2cf5 upstream.
The current number of requestor lines is limited to 31. This was an
error of a previous commit, as this number is platform dependent, and is
actually :
- for pxa25x: 40 requestor lines
- for pxa27x: 75 requestor lines
- for pxa3xx: 100 requestor lines
The previous testing did not reveal the faulty constant as on pxa[23]xx
platforms, only camera, MSL and USB are above requestor 32, and in these
only the camera has a driver using dma.
