exynos/snow: move SPI GPIO setup to mainboard bootblock code
This moves GPIO setup from chip-specific SPI code to mainboard-
specific bootblock code. This makes exynos_spi_open a bit more
generic so it can eventually be used for any SPI channel. This
also benefits CBFS since the user can set media->context to
to any set of SPI registers.
