[U-Boot] [PATCH v2 12/40] i2c: Refactor adapter initialization

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

A subsequent patch will introduce a new API to access I2C adapters
directly rather than going through the bus number and constantly looking
up the same adapter. In order to share the adapter initialization code,
move it into a separate function and make i2c_init_bus() use it to avoid
code duplication.
