hwspinlock: remove now unused pdata from header file

The last user turned out to be obsolete and was removed. Remove the
unused struct now, too.

- * struct hwspinlock_pdata - platform data for hwspinlock drivers
- * @base_id: base id for this hwspinlock device
- *
- * hwspinlock devices provide system-wide hardware locks that are used
- * by remote processors that have no other way to achieve synchronization.
- *
- * To achieve that, each physical lock must have a system-wide id number
- * that is agreed upon, otherwise remote processors can't possibly assume
- * they're using the same hardware lock.
- *
- * Usually boards have a single hwspinlock device, which provides several
- * hwspinlocks, and in this case, they can be trivially numbered 0 to
- * (num-of-locks - 1).
- *
- * In case boards have several hwspinlocks devices, a different base id
- * should be used for each hwspinlock device (they can't all use 0 as
- * a starting id!).
- *
- * This platform data structure should be used to provide the base id
- * for each device (which is trivially 0 when only a single hwspinlock
- * device exists). It can be shared between different platforms, hence
- * its location.
