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.
