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.

Pull ARM/SoC driver updates from Arnd Bergmann:
 "These are updates to SoC specific drivers that did not have another
  subsystem maintainer tree to go through for some reason:

   - Some bus and memory drivers for the MIPS P5600 based Baikal-T1 SoC
     that is getting added through the MIPS tree.

   - There are new soc_device identification drivers for TI K3, Qualcomm
     MSM8939

   - New reset controller drivers for NXP i.MX8MP, Renesas RZ/G1H, and
     Hisilicon hi6220

   - The SCMI firmware interface can now work across ARM SMC/HVC as a
     transport.

   - Mediatek platforms now use a new driver for their "MMSYS" hardware
     block that controls clocks and some other aspects in behalf of the
     media and gpu drivers.

   - Some Tegra processors have improved power management support,
     including getting woken up by the PMIC and cluster power down
     during idle.

   - A new v4l staging driver for Tegra is added.

   - Cleanups and minor bugfixes for TI, NXP, Hisilicon, Mediatek, and
     Tegra"

i.MX SoC changes for 5.8:

- Add soc device support for Vybrid/VF platform.
- Move the i.MX soc device registration code from mach-imx to
  drivers/soc/imx for possible future consolidation with i.MX8 code.
- A small fixup to make pcm970_sja1000_platform_data static.

i.MX drivers update for 5.8:

- Optimize imx-scu driver to use one TX and one RX instead of four for
  talking to SCU.
- Fix one possible message header corruption where the response is
  longer than the request.
- Move System Control defines into dt-bindings header, so that DT can
  use them as well.
- A couple of small fixups.
