lib/test_bitmap: force argument of bitmap_parselist_user() to proper address space

Patch series "gpio: pca953x: Convert to bitmap (extended) API", v2.

While converting gpio-pca953x driver to bitmap API, I noticed that we
have no function to replace bits.

So, that's how patch 7 appears.

First 6 patches are preparatory of the test suite (including some
warning fixes, etc).

Patches 8-9 are preparatory for the GPIO driver to be easier converted
to bitmap API, conversion to which happens in patch 10.

Patch 11 contains simple indentation fixes.

This patch (of 11):

Sparse complains:

  lib/test_bitmap.c:345:58: warning: incorrect type in argument 1 (different address spaces)
  lib/test_bitmap.c:345:58:    expected char const [noderef] <asn:1> *ubuf
  lib/test_bitmap.c:345:58:    got char const *const in

Force argument of bitmap_parselist_user() to proper address space.
