Add AMD dbm690t ACPI support. 

The following ACPI features are supported.
1. S1, S5 sleep and wake up (by power button or PS/2 keyboard/mouse).
2. AMD powernow-k8 driver.
3. Thermal configuration based on ADT7461.
4. IDE timing settings.
5. HPET timer.
6. Interrupt routing based on ACPI table.

/**
* Create the Fixed ACPI Description Tables (FADT) for this board.
The FADT defines various fixed hardware ACPI information vital to an ACPI-compatible
OS, such as the base address for the following hardware registers blocks:
PM1a_EVT_BLK, PM1b_EVT_BLK, PM1a_CNT_BLK, PM1b_CNT_BLK,
PM2_CNT_BLK, PM_TMR_BLK, GPE0_BLK and GPE1_BLK.
The FADT also has a pointer to the DSDT that contains the Differentiated Definition Block,
which in turn provides variable information to an ACPI-compatible OS concerning the base
system design.
Not all blocks are necessary usualy only PM1a, PMTMR and GPE0 are used.
