This patch adds testability of deferred table verification mechanism. As
acpiexec uses dynamically allocated root table list from its very early
stage, a change to acpi_reallocate_root_table() is required to allow deferred
table verification mechanism to be triggered in such an environment. Note
that acpi_gbl_enable_table_validation is still TRUE by default, thus:
1. Developers need to manually set acpi_gbl_enable_table_validation to FALSE
for acpiexec to enable this test.
2. For all other OSPMs (Linux, BSDs, etc.), this commit is a no-op.
