src/include: Add parenthesis around macros

Fix the following error found by checkpatch.pl:

ERROR: Macros with complex values should be enclosed in parentheses

False positives are detected for attribute macros.  An example is:

ERROR: Macros with complex values should be enclosed in parentheses
+#define BOOT_STATE_INIT_ATTR  __attribute__ ((used, section
(".bs_init")))

False positive also generated for macros for linker script files.  An
example is:

ERROR: Macros with complex values should be enclosed in parentheses
+#define CBFS_CACHE(addr, size) \
+	REGION(cbfs_cache, addr, size, 4) \
+	ALIAS_REGION(cbfs_cache, preram_cbfs_cache) \
+	ALIAS_REGION(cbfs_cache, postram_cbfs_cache)

False positives generated for assembly code macros.  An example is:

ERROR: Macros with complex values should be enclosed in parentheses
+#define DECLARE_OPTIONAL_REGION(name) asm (".weak _" #name ", _e" #name
)

False positive detected when macro includes multiple comma separated
values.  The following code is from src/include/device/azalia_device.h:

#define AZALIA_SUBVENDOR(codec, val)		    \
	(((codec) << 28) | (0x01720 << 8) | ((val) & 0xff)),	\
	(((codec) << 28) | (0x01721 << 8) | (((val) >> 8) & 0xff)), \
	(((codec) << 28) | (0x01722 << 8) | (((val) >> 16) & 0xff)), \
	(((codec) << 28) | (0x01723 << 8) | (((val) >> 24) & 0xff))

TEST=Build and run on Galileo Gen2
