[PATCH v1 1/6] arm64: dts: meson: a1: introduce PLL and Peripherals clk controllers

[Dmitry Rokosov <ddrokosov@sberdevices.ru>]

This patch adds clkc and clkc_pll dts nodes to A1 SoC main dtsi.
The first one clk controller is responsible for all SoC peripherals
clocks excluding audio clocks. The second one clk controller is used by
A1 SoC PLLs. Actually, there are two different APB heads, so we have two
different drivers.
