[U-Boot] [PATCH v2] i2c: designware: Convert driver to multibus/multiadapter framework
In preparation for the SoCFPGA support of the designware I2C driver, convert this driver to the common CONFIG_SYS_I2C framework.
This patch converts all users of this driver, this is:
- ST spearxxx boards - AXS101 (ARC700 platform)
I couldn't test this patch on those boards. Only compile tested for all spear boards. And tested on SoCFPGA.
