This patch adds a clock control driver for GD32 platforms. It is important to note that the driver is only able to handle peripheral clocks, but not "system clocks" (e.g. PLL settings, SYS_CK, etc.). On some similar platforms (STM32) this task is embedded in the same clock driver, performed at init time but with no options to do any manipulation at runtime via the API calls. The clock control API as-is is really orthogonal to "system clocks", and it is arguably a bad idea to embed system clock init code in a clock control driver. It can be done at SoC level still using Devicetree as a source of hardware description/initial configuration. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

Enable support for hardware clock controller. Such hardware can
|
|
provide clock for other subsystem, and thus can be also used for
|
|
power efficiency by controlling their clock. Note that this has
|

nothing to do with RTC.
