[ Upstream commit 0310b5aa0656a94102344f1e9ae2892e342a665d ]

The ROHM BD71847 PMIC has a 32.768 kHz clock.

Describe the PMIC clock to fix the following boot errors:

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

Based on the same fix done for imx8mm-evk as per commit
a6a355ede574 ("arm64: dts: imx8mm-evk: Add 32.768 kHz clock to PMIC")

Fixes: 3e44dd09736d ("arm64: dts: imx8mn-ddr4-evk: Add rohm,bd71847 PMIC support")
