Subject: [PATCH part3 1/5] x86, acpi: Call two new functions instead of acpi_initialize_tables() in acpi_table_init().

The previous patches introduces two new functions:
    acpi_initialize_tables_firmware() and acpi_initialize_tables_override(),
which work just the same as acpi_initialize_tables() if they are called
in sequence.

In order to split acpi_table_init() on acpi side, call these two functions
in acpi_table_init().

Since acpi_table_init() is also used in ia64, we keep it works as before.
