xlat_tables_v2: fix signed/unsigned comparisons
xlat_tables_v2: fix signed/unsigned comparisons

This patch changes input param level in xlat_tables_print_internal() to
an unsigned int to fix the signed/unsigned comparison warnings. The
compiler complains about these warnings, thus halting the build flow
for Tegra platforms.
