arm64: dts: meson: a1: introduce PLL and Peripherals clk controllers

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