spi: pxa2xx: Remove CONFIG_SPI_PXA2XX_DMA
After removal of legacy PXA DMA code by the commit 6356437e65c2
("spi: spi-pxa2xx: remove legacy PXA DMA bits") the
CONFIG_SPI_PXA2XX_DMA follows the CONFIG_SPI_PXA2XX and cannot be disabled
alone. Therefore remove this config symbol and dead definitions from the
spi-pxa2xx.h.
