[PATCH 1/3] hwspinlock: sun6i: Get the clock and the reset without names

[Nguyen Minh Tien]

The driver looks up its clock and reset by the name "ahb", but the
binding doesn't define clock-names or reset-names, so a node that
follows the binding fails to probe:

  sun6i_hwspinlock 3005000.hwlock: unable to get AHB clock (-2)

There is only one of each, so get them without a name. That is what
was asked for when the names were added to an A64 node, and nodes that
do set "ahb" keep working. For the reset, call the explicit
devm_reset_control_get_exclusive(), which devm_reset_control_get()
only wraps.
