Subject: [PATCH part1 2/5] acpi, acpica: Call two new functions instead of acpi_tb_install_table() in acpi_tb_parse_root_table().

The previous patch introduced two new functions:
    acpi_tb_install_table_firmware() and acpi_tb_install_table_override().

They are the same as acpi_tb_install_table() if they are called in sequence.

In order to split acpi_tb_parse_root_table(), we call these two functions
instead of acpi_tb_install_table() in acpi_tb_parse_root_table(). This will
keep acpi_tb_parse_root_table() works as before.
