Log:
  aw_sid: Add support for a64
  
  Newer Allwinner SoCs have nearly identical SID controllers with efuse space
  starting at 0x200 into their register space and thermal data available at
  0x234, making all of these fairly trivial additions.
  
  The h3 will be added at a later time after some testing, due to a silicon
  bug that causes the rootkey (at least) to be read incorrectly unless first
  read via the control register.
