Subject[PATCH] spi: pxa2xx: disallow building on MMP
After MMP has become part of a multiplatform build, we can end up with
a randconfig build failure in the pxa2xx spi driver:

drivers/spi/built-in.o: In function `pxa2xx_spi_remove':
:(.text+0x1845c): undefined reference to `pxa_ssp_free'
drivers/spi/built-in.o: In function `pxa2xx_spi_probe':
:(.text+0x19844): undefined reference to `pxa_ssp_request'

What happens here is that we can enable SPI_PXA2XX when some other
platform in the same build supports PCI. This normally works because the
pxa_ssp_request/pxa_ssp_free functions are stubbed out when CONFIG_PXA_SSP
is disabled. However, we can have PXA_SSP=m when that driver is used by
the SND_SOC_TTC_DKB audio driver.

This changes the Kconfig logic to just disallow the pxa2xx SPI
driver on anything but x86 and pxa.
