Here's a couple changes for the i2c-designware driver. Most of them a related to
the support for runtime PM and system PM, but there's also a few that improves
some error handling.
I have tested these on Hisilicon Linaro 96-board (hi6220). I used a couple local
changes to enable the power-key to act as a wakeup in system PM suspend state.
If anyone are interested about those as well, I am happy to share them.

fails

i2c: designware-platdrv: Fix clk gating in ->remove()
i2c: designware-platdrv: Update runtime PM last busy mark in ->probe()
i2c: designware-platdrv: Re-init the HW when resuming
