parisc: pci-dma: fix warning unused-function

Browse Source 
When building tinyconfig on parisc the following warnign shows up:

/tmp/arch/parisc/kernel/pci-dma.c:338:12: warning: 'proc_pcxl_dma_show' defined but not used [-Wunused-function]
 static int proc_pcxl_dma_show(struct seq_file *m, void *v)
            ^~~~~~~~~~~~~~~~~~

Mark the function as __maybe_unused to fix the warning.
