i2c: Drop CONFIG_SOFT_I2C_MULTI_BUS
This is not used by any board. Drop it.
Signed-off-by: Simon Glass <sjg@chromium.org>
Clean up board_f sequence a little
This series tries to remove #ifdefs from the board_f init sequence. It
gets as far as I2C and then we need to discuss whether we can start to
remove the old I2C framework.
I think that ideally each entry in the init sequence should be enabled by
at most one CONFIG, which is in Kconfig and is not arch-specific.
