[PATCH v2] arm64: dts: fix endianness issue of rcpm

[Ran Wang]

From: Biwen Li <biwen...@nxp.com>

Add little-endian property to RCPM node (for ls1028a,ls1088a,ls208xa),
otherwise RCPM driver will program hardware with incorrect setting,
causing system (such as LS1028ARDB) failed to be waked by wakeup source.

Fixes: 791c88ca5713 (“arm64: dts: ls1028a: Add ftm_alarm0 DT node”)
Fixes: f4fe3a8665495 (“arm64: dts: layerscape: add ftm_alarm0 node”)
