Convert CONFIG_SPI to Kconfig
This converts the following to Kconfig:
CONFIG_SPI
This partly involves updating code that assumes that CONFIG_SPI implies
things that are specific to the MPC8xx SPI driver. For now, just update
the CONFIG tests. This also involves reworking the default for
CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
reasonable default, as it does not cause any compile failures.
