i2c: designware: Support use in SPL

Allow this driver to set up an IO address in SPL using an 'early-regs'
property. This allows SPL to use the I2C driver without having to enable
the full PCI stack.

Also split out ofdata_to_platdata in designware driver since this is more
correct, and more convenient for the new logic.
