snlavaiseandClaude Sonnet 5 35df152310 motorola-rtwo: rewrite .dts modelled on mainline Sony Xperia 1 V 
Same SoC, working mainline port. Strip everything speculative:
 - no /memory node (Sony relies on the bootloader to inject it)
 - no qcom,msm-id / qcom,board-id (Sony's Qualcomm bootloader doesn't
   need them)
 - no reserved-memory / ramoops / framebuffer overrides
 - regulator tree copied verbatim from Sony, including the rails it
   deliberately omits with 'the board seems to crash on access' - our
   MTP-derived tree (with vdd-*-supply chains + bob2 + L4) may have been
   voting an RPMh rail that resets the SoC early.
Only the debug UART and USB HS-peripheral are enabled - enough for the
initramfs + USB networking. cmdline: console=ttyMSM0 (no earlycon).
