[PATCH 8/8] spi: Make SPI_S3C64XX=y impossible when EXYNOS_USI_V2=m

[Sam Protsenko <semen.protsenko@linaro.org>]

When S3C64XX SPI is encapsulated in USIv2 block (e.g. in Exynos850),
USIv2 driver must be loaded first, as it's preparing USI hardware for
particular protocol use. Make it impossible for spi-s3c64xx driver to be
built-in when USIv2 driver is built as a module, to prevent incorrect
booting order for those drivers.
