sh: Convert iounmap() macros to inline functions

Browse Source 
Macro iounmap() do nothing, but that results in
unused variable warnings all over the place.
This patch convert it to inline to avoid warning

We will get this warning without this patch

	${LINUX}/drivers/thermal/broadcom/ns-thermal.c:78:21: \
	  warning: unused variable 'ns_thermal' [-Wunused-variable]
	struct ns_thermal *ns_thermal = platform_get_drvdata(pdev);
	^~~~~~~~~~
