[PATCH] soc: imx: check ls1021a

[peng.fan at nxp.com]

From: Peng Fan <peng.fan at nxp.com>

fsl,ls1021a is a mach under arch/arm/mach-imx/, however it could
not use the soc driver which will break caam on ls1021a platform.

So directly return if it is compatible with fsl,ls1021a.

Fixes: 52102a3ba6a61 ("soc: imx: move cpu code to drivers/soc/imx")
