Hudson: Changes to agesa/hudson FADT for ACPI 3.0

Update the southbridge/amd/agesa/hudson FADT generation for ACPI
3.0 compliance similar to what was done for cimx/SB800/fadt.c in
commit 9aa4389.

    commit 9aa43892e6
    Author: Martin Roth <martin@se-eng.com>
    Date:   Fri May 25 12:23:32 2012 -0600

        Update SB800 CIMX FADT

According to the datasheet, PMA_CNT_BLK is no longer available
and PM2_CNT_BLK should not be used.  Setup for these has been
removed from the table and .h file.
