Commit f9b6a1575d9f1ca192e4cb60e547aa66f08baa3f, "i.MX31: fix SPI driver for shorter than 32 bit" broke 32 bit transfers. This patch makes single 32 bit transfer work again.
Transfer lengths that are known not to work will abort and print an error message.
Tested on i.MX31 Litekit and i.MX31 PDK using 32 bit transfers to the MC13783/ATLAS chip (using the 'date' command).

As discussed on the mailing list, Guennadi Liakhovetski thinks that all transfers > 16 bits are broken. This patch fixes the 32 bit case and makes sure the user is notified if a broken bitlength is used.
