ACPICA: Tables: Change table duplication check to be related to acpi_gbl_verify_table_checksum

ACPICA commit 3d837b5d4b1033942b4d91c7d3801a09c3157918

acpi_gbl_verify_table_checksum is used to avoid validating (mapping) an entire
table in OS boot stage. 2nd "Reload" check in acpi_tb_install_standard_table()
is prepared for the same purpose. So this patch combines them together
using a renamed acpi_gbl_enable_table_validation flag. Lv Zheng.
