ACPICA: Tables: Avoid SSDT installation with acpi_gbl_disable_ssdt_table_load.
It is reported that when acpi_gbl_disable_ssdt_table_load is specified, user still can see it installed into /sys/firmware/acpi/tables on Linux boxes. This is because the option only stops table "loading", but doesn't stop table "installing", thus it is still in the acpi_gbl_root_table_list. With previous cleanups, it is possible to prevent SSDT installations to make it not such confusing. The global variable is also renamed. Lv Zheng.
