The Synopsys I2C Controller has a bus clock that some SoCs require to access
the registers. This series also details the new clock property in the bindings
documentation.

v3:
 - busclk renamed to pclk.
 - Added comment with dw_i2c_dev struct definition describing pclk.
 - Added enable rollback of first clock if second fails to enable.
 - Changed clocks and clock-names sections to use term "peripheral clock"
   (pclk) instead of "bus clock" (busclk) in dt-bindings documentation.
v2:
 - Use new devm_clk_get_optional() function as it simplifies handling when
   the optional clock is not present.
