sh: convert nommu io{re,un}map() to static inline functions

Recently, nommu iounmap() was converted from a static inline function to a
macro again, basically reverting commit 4580ba4ad2e6b8dd ("sh: Convert
iounmap() macros to inline functions").  With -Werror, this leads to build
failures like:

    drivers/iio/adc/xilinx-ams.c: In function `ams_iounmap_ps':
    drivers/iio/adc/xilinx-ams.c:1195:14: error: unused variable `ams' [-Werror=unused-variable]
     1195 |  struct ams *ams = data;
	  |              ^~~

Fix this by replacing the macros for ioremap() and iounmap() by static
inline functions, based on <asm-generic/io.h>.
