imx7s/imx7d has the ptp interrupt newly added as well.

For imx7, "int0" is the interrupt for queue 0 and ENET_MII
"int1" is for queue 1
"int2" is for queue 2

For imx6sx, "int0" handles all 3 queues and ENET_MII

And of course, the "pps" interrupt is for the PTP_CLOCK_PPS interrupts

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

Commit 7f107887 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.

Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.
