Summary

Implement support for AHCI controller found in
NXP QorIQ Layerscape SoCs.

Do you know how different this controller is compared to the other fsl ahci controller ? (like ls208x etc ...)
If it's very different the file should be renamed.

Add dependency on SOC_NXP_LS1046A option.

I checked and while there will be some modifications needed, I think that most of the code can be shared.

There is no clock enabling here but the dtsi have a clock property.

I don't know if your client requires it but it's been deprecated in FreeBSD.

The controller is actually connected to platform PLL, which
is always enabled, but since the controller might be used in
different SoC in the future, I'll add clock enabling.

I will remove it.
