To be able to use the three none AO uarts of the meson gx SoCs (uart_A,
uart_B & uart_C), the core clock has to be enabled (see chapter 22.3 of
the public s905 data sheet).
At least the u-boot of my s905 based media player (netxeon minimx-g)
doesn't do this. so the driver must enable the clock.

This patch set does:
- exposes the UART clock ids to the dtb
- adds documentation for the dt-bindings of meson_uart
- adds the core clock handling to the driver
- adds the core clock handling to meson-gxbb.dtsi and meson-gxl.dtsi

The patchset is based on the branch "master" of the repository in [1]

Changes since v2
- mail subjects reworked
- add clocks/clock-names to the documentation
- add core clock handling to meson-gxbb.dtsi & meson-gxl.dtsi

Changes since v1
- use git to produce the patch set
- added the clock ids for uart_B and uart_C
