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.
