Add the fsl,aipi-bus and fsl,emi-bus compatible strings for i.MX1 and i.MX2 variants. These compatibles are only intended for existing legacy chips (more than 15 years old) and will not be used for new device trees.

The AST2600's ACRY (eliptic curve and RSA crypto engine) requires access to configuration exposed by the AHB controller. The devicetree already describes the AHB controller node as a syscon, so require this in the binding to satisfy the ACRY relationship.

Pull SoC driver updates from Arnd Bergmann:
"This is the first half of the driver changes:
- A treewide interface change to the "syscore" operations for power
management, as a preparation for future Tegra specific changes
- Reset controller updates with added drivers for LAN969x, eic770 and
RZ/G3S SoCs
- Protection of system controller registers on Renesas and Google
SoCs, to prevent trivially triggering a system crash from e.g.
debugfs access
- soc_device identification updates on Nvidia, Exynos and Mediatek
- debugfs support in the ST STM32 firewall driver
- Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI
- Cleanups for memory controller support on Nvidia and Renesas"
