ata: brcm: mark PM functions as __maybe_unused
The new shutdown callback causes a link failure:
drivers/ata/ahci_brcm.c: In function 'brcm_ahci_shutdown':
drivers/ata/ahci_brcm.c:552:8: error: implicit declaration of function 'brcm_ahci_suspend'; did you mean 'brcm_ahci_shutdown'? [-Werror=implicit-function-declaration]
ret = brcm_ahci_suspend(&pdev->dev);
^~~~~~~~~~~~~~~~~
Remove the incorrect #ifdef and use __maybe_unused annotations
instead to make this more robust.
Fixes: 7de9b1688c1d ("ata: ahci_brcm: Add a shutdown callback")
