[3/3] ARM: dts: meson8b: add the DDR clock controller

Commit Message

Martin Blumenstingl Dec. 8, 2019, 6:05 p.m. UTC

Add the DDR clock controller and pass it's DDR_CLKID_DDR_PLL to the main
(HHI) clock controller as "ddr_clk". The "ddr_clk" is used as one of the
inputs for the audio clock muxes.
