[v4,15/18,automated] Use OBJECT_DECLARE_TYPE where possible

Commit Message

Eduardo Habkost Aug. 31, 2020, 9:07 p.m. UTC

Replace DECLARE_OBJ_CHECKERS with OBJECT_DECLARE_TYPE where the
typedefs can be safely removed.

Generated running:

$ ./scripts/codeconverter/converter.py -i \
  --pattern=DeclareObjCheckers $(git grep -l '' -- '*.[ch]')

Changes v3 -> v4: none

Changes v2 -> v3:
* Removed hunks due to rebase conflict: include/hw/ppc/xive.h
  include/hw/arm/armsse.h
* Reviewed-by line from Daniel was kept, as no additional hunks
  are introduced in this version

Changes v1 -> v2:
* Script re-run after typedefs and macros were moved, and now the
  patch also touches:
  - TYPE_ARM_SSE
  - TYPE_SD_BUS
