USB: storage: ums-realtek: Whitelist auto-delink support

Auto-delink requires writing special registers to ums-realtek devices.
Unconditionally enable auto-delink may break newer devices.

So only enable auto-delink by default for the original three IDs,
0x0138, 0x0158 and 0x0159.

Realtek is working on a patch to properly support auto-delink for other
IDs.
