When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

<linux/sched/task.h>
We are going to split <linux/sched/task.h> out of <linux/sched.h>, which
will have to be picked up from other headers and a couple of .c files.
Create a trivial placeholder <linux/sched/task.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.
Include the new header in the files that are going to need it.

The Makefile/Kconfig currently controlling compilation of this code is:
obj-$(CONFIG_DEBUG_FS) += $(debugfs-y)
debugfs-y := asids-debugfs.o
lib/Kconfig.debug:config DEBUG_FS
lib/Kconfig.debug: bool "Debug Filesystem"
....meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular code, so that when reading the
driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

While sh previously had its own debugfs root, there now exists a
common arch_debugfs_dir prototype, so we switch everything over to
that. Presumably once more architectures start making use of this
we'll be able to just kill off the stub kdebugfs wrapper.

This ought to be unsigned long, rather than defaulting to int.

This converts the sh64 /proc/asids entry to debugfs and enables it for
all SH parts that have debugfs enabled.
On MMU systems this can be used to determine which processes are using
which ASIDs which in turn can be used for finer grained cache tag
analysis.
