[ Upstream commit 7e71b85473f863a29eb1c69265ef025389b4091d ]

U-Boot attempts to fix up the "clock-frequency" property of the "/sysclk" node:
https://elixir.bootlin.com/u-boot/v2021.04/source/arch/arm/cpu/armv8/fsl-layerscape/fdt.c#L512

but fails to do so:

## Booting kernel from Legacy Image at a1000000 ...
Image Name:
Created: 2021-06-08 10:31:38 UTC

Uncompressing Kernel Image

Unable to update property /sysclk:clock-frequency, err=FDT_ERR_NOTFOUND

Starting kernel ...

All Layerscape SoCs except LS1028A use "sysclk" as the node name, and
not "clock-sysclk". So change the node name of LS1028A accordingly.
