[PATCH 8/8] wl12xx: drop unneeded plat_dev

[Luciano Coelho <coelho@ti.com>]

From: Felipe Balbi <balbi@ti.com>

now that useless plat_dev is unnecessary,
we can remove it.

[forward ported and fixed sysfs file creation]

Moved sysfs file creation to the end of the probe function instead of
doing it in the hw_alloc() function.  It's too early to do it in
hw_alloc, because we don't have wl->dev at that point yet.
