[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.
