[v1,3/4] ARM: dts: imx8qm-apalis: dm-pre-proper for pd_dma nodes

From: Igor Opaniuk <igor.opaniuk at toradex.com>

pd_dma_* nodes should be accessible during pre-relocation stage of
U-Boot proper for properly handling power domains.

This fixes the issue with permanent failing of invocation of
power_domain_get_by_index() in the common code of DM power domain
uclass (drivers/power/domain/power-domain-uclass.c).

Fixes: f0cc4eae9a ("core: device: use dev_power_domain_on")
