[PATCH 3/3] hwspinlock/core: allow hwspinlock_device to have bank-specific private data

[Shinya Kuribayashi <shinya.kuribayashi.px@xxxxxxxxxxx>]

It would be useful, for example, to save ioremap()ed 'io_base' address,
when a platform-specific driver uses 'priv' in 'struct hwspinlock' for
something different.
