ACPI: fix empty macros found by -Wextra
ACPI has a ton of macros which make a bunch of empty if's when configured
in non-debug mode.
[lenb: The code it complaines about is functionally correct,
so this patch is just to make -Wextra happier]
#define DBG()
if(...)
DBG();
next_c_statement
which turns into
if(...) ;
next_c_statement
