ARM: dts: imx: use generic name bus

Synchronize the u-boot and kernel imx device trees, using tuned
script from commit c0157bdcafa1 ("ARM: dts: imx: use generic name bus")

Per devicetree specification, generic names are recommended to be
used, such as bus.

i.MX AIPS is an AHB - IP bridge bus, so we could use bus as node
name.

Script:
sed -i "s/\<aips@/bus@/" arch/arm/dts/imx*.dtsi
sed -i "s/\<aips@/bus@/" arch/arm/dts/vf*.dtsi
sed -i "s/\<aips-bus@/bus@/" arch/arm/dts/imx*.dtsi
sed -i "s/\<aips-bus@/bus@/" arch/arm/dts/vf*.dtsi
