[PATCH] smc91x: disable DMA mode on the logicpd pxa270 



Enabling PXA DMA for the smc91x on the logicpd pxa270 produces
unacceptable interference with the TFT panel, so disable it.  Also
delete the lpd270 versions of the SMC_{in,out}[bl]() macros, as they
aren't used, since the board only supports 16bit accesses.
