pata_platform: Fix NULL pointer dereference
pata_platform currently dereferences a NULL pointer in pata_platform_probe()
if pdev->dev.platform_data is set to NULL. This breakage was most likely
introduced by commit 5f45bc50976ee1f408f7171af155aec646655a37.

Tested on a Solution Engline 7722 board, fixes NULL dereference problem.
Applies to linux-2.6 git 9a79b2274186fade17134929d4f85b70d59a3840
Could someone please make sure this gets included in rc1?
