Philippe Mathieu-Daudé Dec. 12, 2023, 12:33 p.m. UTC 
accel/tcg/ files requires the following definitions:

  - TARGET_LONG_BITS
  - TARGET_PAGE_BITS
  - TARGET_PHYS_ADDR_SPACE_BITS
  - TCG_GUEST_DEFAULT_MO

The first 3 are defined in "cpu-param.h". The last one
in "cpu.h", with a bunch of definitions irrelevant for
TCG. By moving the TCG_GUEST_DEFAULT_MO definition to
"cpu-param.h", we can simplify various accel/tcg includes.
