Oops, missed that. Will fix it in v2.

Oh, ok, I thought of keeping all boards based on sm8150 SoC together.
But alphabetically, it makes more sense to put it earlier.

While a few labels like 'vdd_usb_hs_core' are used in this patch (for
example) to denote 'vdda-pll-supply ' of 'usb_1_hsphy', the others
would be required as we enable further on-boards peripherals in the
dts.

I will recheck and limit these further in v2.

That's a good point. Will fix this in v2.
