This is the same as `debugfs_create_file()` but takes the initial size
of the file. In FreeBSD, the given size is ignored and
`debugfs_create_file()` is called.

The `debugfs_create_x*()` variants are the same as their
`debugfs_create_u*()` equivalent, but they work with lowercase
hexadecimal.
While here, fix a few style(9) issues.

Add debugfs_create_u8() based on other already present implementations.
Add a read-only implementation for debugfs_create_blob().
Both are needed for iwlwifi debugfs support.

This diff extends LinuxKPI to support simple attribute files in debugfs.
These simple attributes are an essential component for compiling drm-kmod
with CONFIG_DEBUG_FS enabled.
This will allow for easier graphics driver debugging using
Intel's igt-gpu-tools.

The source file was moved to base earlier and also improved upon,
but never compiled in. This patch will:
- Make a module in sys/modules
- Make lindebugfs depend on linuxkpi (for seq_file)
- Check if read/write functions are set before calling, DRM drivers
don't always set both of them.
