sparc: Fix parport build warnings.
[ Upstream commit 46b8306480fb424abd525acc1763da1c63a27d8a ]
If PARPORT_PC_FIFO is not enabled, do not provide the dma lock
macros and lock definition. Otherwise:
./arch/sparc/include/asm/parport.h:24:24: warning: ‘dma_spin_lock’ defined but not used [-Wunused-variable]
static DEFINE_SPINLOCK(dma_spin_lock);
^~~~~~~~~~~~~
./include/linux/spinlock_types.h:81:39: note: in definition of macro ‘DEFINE_SPINLOCK’
#define DEFINE_SPINLOCK(x) spinlock_t x = __SPIN_LOCK_UNLOCKED(x)
