Add driver and MAINTAINERS for HiSilicon I2C controller on Kunpeng SoC. Also
provide the devm_*() variants for adding the I2C adapters. Add a public
api to provide I2C frequency mode strings and convert designware driver
to use it.
Change since v4:
- and Andy's review-by
- attach Andy's patch of switch designware driver to use i2c_freq_mode_string()

Change since v3:
- split the bus mode string api to I2C as suggested by Andy
- simplify the devm variants and change the export format
- address the comments of the HiSilicon I2C driver from Andy and Dmitry, thanks!

Change since v2:
- handle -EPROBE_DEFER case when get irq number by platform_get_irq()
Link: https://lore.kernel.org/linux-i2c/1615296137-14558-1-git-...
Change since v1:
- fix compile test error on 32bit arch, reported by intel lkp robot:
64 bit division without using kernel wrapper in probe function.
