[Skiboot] [PATCH v2 3/3] libflash/file: Use 64bit ioctl() to erase from MTD

[Cyril Bur]

While we'll 'never' have flash chips larger than 32bit, work was
recently done to blocklevel for it to be 64bit compatible for other
backends.

Since there is a 64bit ioctl() lets use it. There is currently no known
case where 32bit is not sufficient but this doesn't mean someone might
not do something strange in the future.
