ACPICA: Tables: Cleanup ACPI_TABLE_ORIGIN_xxx flags.
This patch refines ACPI_TABLE_ORIGIN_xxx flags. No functional changes. The previous commits have introduced the following internal APIs: 1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 2. acpi_tb_release_table: Release struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to ACPI_TABLE_ORIGIN_xxx flags. 5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to ACPI_TABLE_ORIGIN_xxx flags. It thus detects that the ACPI_TABLE_ORIGIN_UNKNOWN is redundant to ACPI_TABLE_ORIGIN_OVERRIDE. The ACPI_TABLE_ORIGIN_xxTERN_VIRTUAL flags are named as VIRTUAL in order not to confuse with x86 logical address, this patch also renames all "logical override" into "virtual override".
