arm64: dts: qcom: sc7280: Add herobrine-r1

Add the new herobrine-r1. Note that this is pretty much a re-design
compared to herobrine-r0 so we don't attempt any dtsi to share stuff
between them.

This patch attempts to define things at 3 levels:

1. The Qcard level. Herobrine includes a Qcard PCB and the Qcard PCB
   is supposed to be the same (modulo stuffing options) across
   multiple boards, so trying to define what's there hopefully makes
   sense. NOTE that newer "CRD" boards from Qualcomm also use
   Qcard. When support for CRD3 is added hopefully it can use the
   Qcard include (and perhaps we should even evaluate it using
   herobrine.dtsi?)
2. The herobrine "baseboard" level. Right now most stuff is here with
   the exception of things that we _know_ will be different per
   board. We know that not all boards will have the same set of eMMC,
   nvme, and SD. We also know that the exact pin names are likely to
   be different.
3. The actual "board" level, AKA herobrine-rev1.

NOTES:
- This boots to command prompt. We're still waiting on the PWM driver.
- This assumes LTE for now. Once it's clear how WiFi-only SKUs will
  work we expect some small changes.
