imx233: increase max dma transfer size
The old max dma transfer size was set to 2^15 because allowing
values up to 2^16 would result in overflow of the transfer count
in many places. This was a problem with the old register headers
because the macros didn't make sure the result is contained in
the bitmask of the field. The new macro do so 2^16 will actually
end up being 0 which means 2^16 for the hardware. This is kind of
hacky but it works and I prefer that this stays a power of two
because setting it to 2^16-1 would be extremely weird.
