mmc: Add dependency to openpower-update-bios-attr-table.service

The openpower-update-bios-attr-table.service creates symlinks to lid
files is the partition files do not exist. The service
openpower-process-host-firmware.service creates symlinks to the well
known firmware name by deleting the base partition file and creting a
symlink. If both services run at the same time, they can interfere,
causing the bios attr service to create a symlink when it's not desired
(it thinks the file doesn't exist but it's because the process host fw
service just deleted it to create its symlink). Add a dependency to
serialize them.
