Subject: [PATCH] hwrng: xgene: Add explicit io.h include

Commit 0788257aeebe ("hwrng: Explicitly include correct DT includes")
removed an implicit include of io.h. On most architectures, there's
still an implicit include of it, but not on s390. Enabling COMPILE_TEST
in commit 1ce1cd8208ad ("hwrng: Enable COMPILE_TEST for more drivers")
exposed this.

Fixes: 0788257aeebe ("hwrng: Explicitly include correct DT includes")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202308042049.8R2tNRoo-lkp@intel.com/
