ata: pata_pxa: Fix potential NULL pointer dereference in pxa_ata_probe()
devm_ioremap() returns NULL on error. Currently, pxa_ata_probe() does
not check for this case, which can result in a NULL pointer dereference.
Add NULL check after devm_ioremap() to prevent this issue.
Fixes: 2dc6c6f15da9 ("[ARM] pata_pxa: DMA-capable PATA driver")
