clocksource/drivers: Fix various !CONFIG_HAS_IOMEM build errors

Fix !CONFIG_HAS_IOMEM related build failures in three clocksource drivers.

The build failures have the pattern of:

  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));
