mtd: maps: vmu-flash: fix NULL pointer dereference in initialization

Browse Source 
The mtd_info contains a struct device, which must be linked to its
parent. Without this, the initialization of the MTD fails with a NULL
pointer dereference.

Fixes: 47a72688fa ("mtd: flash mapping support for Dreamcast VMU.")
