[U-Boot] [PATCH 17/17] i2c: Drop CONFIG_SOFT_I2C_MULTI_BUS

[Lukasz Majewski <lukma@denx.de>]

Hi Simon,

+CC board maintainer: Jaehoon.

> This is not used by any board. Drop it.

> 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. END
