Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information". Nothing to convert there; skipped.
Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Converted manually.
A few line breaks tidied up manually.
