This patch changes the ISA Kconfig option dependency of the WinSystems EBC-C384 watchdog timer driver to ISA_BUS_API, thus allowing it to build for X86_64 as it is expected to.

Mostly just debugfs changes, the long-known and messy races with removing debugfs files should be fixed thanks to the great work of Nicolai Stange. We also have some isa updates in here (the x86 maintainers told me to take it through this tree), a new warning when we run out of dynamic char major numbers, and a few other assorted changes, details in the shortlog.

The primary function of the deadman timer (DMT) is to reset the processor in the event of a software malfunction. The DMT is a free-running instruction fetch timer, which is clocked whenever an instruction fetch occurs until a count match occurs. Instructions are not fetched when the processor is in sleep mode.
