This patch adds support for a watchdog in IT8721F Super IO
chip to it87_wdt driver.
This new chips differ from the older IT87xxxF chips 
in the following ways:

* WDT_GAMEPORT is not in IT8721F.
* WDT_PWROK is not in IT8721F.

Builds the hpwdt driver as a module by default.
If the hardware is present, the module will be loaded.
Also, if hpwdt is loaded, it will decode NMIs by default.

This has been made possible by he patches to hpwdt made by Dann Frazier
as well as related patches submitted by Don Zickus.

hpwdt only loads on hp ProLiant x86 32-bit and 64-bit platforms.

The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout
value in the code based on whether it's a Freescale Book-E part of not.
Instead of having hard-coded values in the driver, make it a Kconfig
option.

As newer chips gets faster, the current default values become less
appropriate, since the timeout sometimes occurs before the kernel finishes
booting.  Making the value a Kconfig option allows BSPs to configure a new
value without requiring the wdt_period command-line parameter to be set.

Add a .release method for the PowerPC Book-E Watchdog driver, so that the

This driver supports both iLO2 and iLO3, but our user-visible strings
currently only reference iLO2. Let's just call it "iLO2+" to avoid having
to update strings for each iLO generation. This driver doesn't support
iLO ASICs prior to iLO2, but that is sufficiently explained in Kconfig.

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

The driver is split into two source files one for the C code and one
for assembly.  Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.
