Add dts nodes for apps_smmu and USB for both sm8150 and sm8250.


I've tested this series on an SM8250 based board and able to get Type C (USB0)
working. There are also couple of Type A ports (USB1) on that board behind a
USB hub. It is probing fine but I don't see any activity while connecting a
USB device. Will continue to debug and once I get them working, I'll add my
Tested-by tag.


HDK865 also has a couple Type A ports, I am using them with devices already
plugged in during boot and I haven't hit a problem like that, but I think
I've seen the same issue when hotplugging. IIRC the behavior was a bit
weird, like plugging a device in the Type A port (USB1) nothing would
happen, but unplugging/replugging the type C port (USB0) would cause the
Type A port device to start working..

Have you tried with the devices already plugged in before booting?


Tried it but no luck :/ Also plugging and removing Type C doesn't make any
difference.


This one might be obvious, but do you have 5V power coming out of the type A ports?

Thanks,

Also add initial dts files for HDK855 and HDK865, based on mtp dts, with a
few changes. Notably, the HDK865 dts has regulator config changed a bit based
on downstream (I think sm8250-mtp.dts is wrong and copied too much from sm8150).
