Functions memremap_is_setup_data() and early_memremap_is_setup_data()
share completely the same process and handling, except of the
different memremap/unmap invocations. The code can be extracted and put
into a helper function __memremap_is_setup_data().

And parameter 'size' is unused in implementation of memremap_is_efi_data(),
memremap_is_setup_data and early_memremap_is_setup_data().

This patchset is made to clean them up. 

v2->v3:
- Add back __init to early_memremap_is_setup_data(). Tom pointed out
  this.
- Split out the defining and usage of SD_SIZE and put them in patch 2.
  Suggested by Ingo.

v1->v2:
- Remove __init from helper __memremap_is_setup_data(), add __ref to
  helper suppress mismatch section warning.
- Merge the old patch 1 and 2 into one patch.
  - Both are suggested by Tom during reviewing. Thanks to him.
