[PATCH] arm64: dts: imx8mm-var-som: Add 32.768 kHz clock to PMIC

From: Krzysztof Kozlowski <krzk@kernel.org>
Date: 2020-09-02 16:32:45

The ROHM BD71847 PMIC has a 32.768 kHz clock.  Adding necessary parent
allows to probe the bd718x7 clock driver fixing boot errors:

    bd718xx-clk bd71847-clk.1.auto: No parent clk found
    bd718xx-clk: probe of bd71847-clk.1.auto failed with error -22
