Consolidate the timeout config register modification into a single
function.  Also, use the enabled flag in the config register to
determine whether the timer is enabled instead of a separately
maintained flag, MV64x60_WDOG_FLAG_ENABLED.

Add spinlock protection around enabling/disabling the watchdog timer.

Previously, the address of the watchdog timer registers was
retrieved by calling a global function, mv64x60_get_bridge_vbase().
That function doesn't exist in arch/powerpc.  Instead, we now get

the registers within the driver.

The driver previously registered its platform device data in its own

1. Ensure that the mouse and keyboard do not ping the watchdog.
This is the default operation of the w83627, but some BIOSes change this.

2. Increase the max timeout from 63 seconds to 255 seconds
as supported by the w83627 chip

3. Comment that the watchdog supports the w83627hg version of the chip

Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3

All static tables (besides teh RSDP and RSDT themselves

are not declared in the RSDT, will be added in a subsequent patch.

Split ACPI_DEBUG into function trace enabled and not enabled.

Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.

Size of kernel image increased on test compile:
+ 48k  (Full ACPI_DEBUG)
+ 35k  (ACPI_DEBUG with function trace compiled out)

Performance without function trace is also much better.

Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.
