SH_TIMER_CMT will use IO memory features which needs HAS_IOMEM, so need
depend on it. One of the related error (with allmodconfig under um):
CC drivers/clocksource/sh_cmt.o
drivers/clocksource/sh_cmt.c: In function 'sh_cmt_map_memory':
drivers/clocksource/sh_cmt.c:920:2: error: implicit declaration of function 'ioremap_nocache' [-Werror=implicit-function-declaration]
cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem));
^
drivers/clocksource/sh_cmt.c:920:15: warning: assignment makes pointer from integer without a cast [enabled by default]
cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem));
