  There is need to enble CLEARPBA bit for ice NIC of A0/A1 version
in order to enable admin queue interrupt in avf mode.
If not, avf will not work.

Reword to

Enable CLEARPBA bit is required by ice NIC of A0/A1 version to
enable admin queue interrupt.
Also enable CLEARPBA bit does no impact on AVF behaviour when be
hosted by other devices, so we can make it as default.
