[PATCH part1 4/5] acpi, acpica: Call two new functions instead of acpi_tb_parse_root_table() in acpi_initialize_tables().

[Tang Chen <tangchen@cn.fujitsu.com>]

The previous patch introduces two new functions:
    acpi_tb_root_table_install() and acpi_tb_root_table_override(),
which work just the same as acpi_tb_parse_root_table() if they are
called in sequence.

In order to split acpi_initialize_tables(), call thes two functions
in acpi_initialize_tables(). This will keep acpi_initialize_tables()
works as before.
