First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig. Next, as you cannot have SYS_I2C_LEGACY and DM_I2C at the same time, introduce CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only in SPL. Finally, for some PowerPC cases we also need CONFIG_TPL_SYS_I2C_LEGACY support. Convert all of the existing users to one or more symbols. Signed-off-by: Tom Rini <trini@konsulko.com>
