Jeff Johnston 5eb4a1666d or1k: set heap start for optimsoc-gzll
- With the gzll kernel we have two different loading options:

  - If the image is loaded to the global memory, the bootstrapping
    loads the kernel to local memory. Applications are loaded on
    demand. The heap then starts right after bss.

  - If the image is pre-loaded to the local memory it includes the
    application binaries right after bss. The heap then starts after
    the application objects.

- We can check if this is a gzll kernel as it has the string "gzll" at
  0x2000. At 0x200c we then find the end of the application objects in
  the image. If there is no global memory we set _or1k_heap_start to
  this value.

Jeff Johnston 58efeedd16 or1k: Make heap start configurable
- Previously the heap started right after the bss section. This can now
  be configured by changing the _or1k_heap_start symbol that defaults to
  the old value (&end). In board_init_early, we can now set this to
  another value.

- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
  line in r22. Those are callee-saved registers, so that the register
  values will be preserved.
