src/include: Add do { } while(0) around macros 

Fix the following error detected by checkpatch.py:

ERROR: Macros with multiple statements should be enclosed in a do - while loop

False positives are generated when assembly code is used in a macro.  An
example is:

ERROR: Macros with multiple statements should be enclosed in a do - while loop
+#define post_code(value)        \
+	movb    $value, %al;    \
+	outb    %al, $CONFIG_POST_IO_PORT

False positives are also generated for linker script include files.  An
example is:

ERROR: Macros with multiple statements should be enclosed in a do - while loop
+#define SET_COUNTER(name, addr) \
+	_ = ASSERT(. <= addr, STR(name overlaps the previous region!));
\
+	. = addr;

False positives are also generated for attribute macros.  An example is:

ERROR: Macros with multiple statements should be enclosed in a do - while loop
+#define DISABLE_TRACE_ON_FUNCTION  __attribute__
((no_instrument_function));

TEST=Build and run on Galileo Gen2
