[PATCH 1/1] SPI: disable CONFIG_SPI_FSL_ESPI=m build

[Jiri Slaby]

When spi_fsl_espi is chosen to be built as a module, there is a build
error because we test only CONFIG_SPI_FSL_ESPI in declaration of
struct mpc8xxx_spi in drivers/spi/spi_fsl_lib.h. Also some called
functions are not exported.

So we forbid CONFIG_SPI_FSL_ESPI to be tristate here.

The error looks like:
drivers/spi/spi_fsl_espi.c: In function 'fsl_espi_bufs':
drivers/spi/spi_fsl_espi.c:232: error: 'struct mpc8xxx_spi' has no member named 'len'
...
