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.
We need to add a test for CONFIG_SPI_FSL_ESPI_MODULE too.
The error looks like:

Rounding up lower divisors makes the error too big, causing USB
on MPC832x to fail.

Hi,
We had some questions as to why we have this totally separate driver
