    ACPI: processor: call _PDC early

because dynamic SSDT tables may be loaded in _PDC,
before installing the ACPI table handler.
As a result, the sysfs I/F of these dynamic tables are
located at  /sys/firmware/acpi/tables instead of
/sys/firmware/acpi/tables/dynamic, which is not true.

Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(),
so that the table handler is installed before any dynamic tables loaded.
