Series bulk: Replace CONFIG_SOFTMMU by !CONFIG_USER_ONLY/CONFIG_SYSTEM_ONLY | expand

Commit Message

Philippe Mathieu-Daudé June 13, 2023, 1:33 p.m. UTC 
Since we *might* have user emulation with softmmu,
replace the system emulation check by !user emulation one.

Invert some if() ladders for clarity.
