Clean up read_vmcore(). Part for objects in vmcore_list can be written

Hello,
Contiguous Memory Allocator is very sensitive about migration failures
of the individual pages. A single page, which causes permanent migration
failure can break large conitguous allocations and cause the failure of

I did come to the same conclusion regarding the platform data breakage.
I'm expecting that the use of platform data will go away, at
W83667HG-B, NCT6775, NCT6776 have the same watchdog registers as the
other supported chips but require a slightly different initialization.

Major difference is that the watchdog control and counter registers
are different on both chips.

Since both chips are now supported by the w83627hf watchdog driver,
the chip specific drivers are no longer needed and can be removed.

There is no need to enable the watchdog device if it is already enabled.
Also, when enabling the watchdog device, only set the watchdog device
enable bit and do not touch other bits; depending on the chip type,
those bits may enable other functionality.

Instead of requiring the user to provide an IO address per module
parameter, auto-detect it as well as supported chips.

It is unnecessary to enable the logical device and WDT0 each time
the watchdog is accessed. Do it only once during initialization.

Use helper functions named similar to other drivers to access
superio registers.

Convert to watchdog infrastructure, cleanup, add support for additional
chips, and merge with W83697HF and W83697UG watchdog drivers.
Tested with NCT6775 and NCT6776. I'll be able to test the code with W83627UHG.
Additional test feedback, especially for other chips, would be appreciated.

This patch uses module_platform_driver_probe() macro which makes
the code smaller and simpler.
