[PATCH v2] systemd: apply persistent storage udev rules also for /dev/hd*

[Patrick Ohly <patrick.ohly@intel.com>]

This fixes booting with initramfs and root=UUID on machines with IDE
disks, like "runqemu hdddirect", and kernels which still use the
deprecated CONFIG_IDE.

v2: Rebased against current master-next.

+Subject: [PATCH] rules: whitelist hd* devices
+
+qemu by default emulates IDE and the linux-yocto kernel(s) use
+CONFIG_IDE instead of the more modern libsata, so disks appear as
+/dev/hd*. Patch rejected upstream because CONFIG_IDE is deprecated.
