ps3: Replace direct file operations by callback
Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example. Replace the file operations by callbacks, registered by the ps3flash driver.
