motorola-rtwo: no earlycon, clean /chosen, framebuffer at root

Browse Source 
New hypotheses from re-comparing with the stock boot:
- 'earlycon' (bare) brings up uart7 in setup_arch(), before the clock
  framework. Stock uses console=null and almost certainly leaves the
  QUP0 clock gated -> touching uart7 MMIO faults before any console.
  Drop earlycon + the serial console; keep console=tty0 only.
- Also drop clk_ignore_unused / pd_ignore_unused (can break qcom power
  domain init) and ignore_loglevel stays for the fb console.
- Move the simple-framebuffer out of /chosen and drop the
  #address-cells override there, so the bootloader's /memory + initrd
  patching into /chosen is not disturbed.
