msm: ipa: enable HOLB on IPA producer pipes for IPA 2.0

On IPA 1.1 suspending a pipe results in immediate packet drop. On IPA 2.0
the behavior has changed and the packets stall IPA, while raising an
interrupt to SW. This change enables Head Of Line Blocking, which results
in the same behavior on IPA 2.0 and IPA 1.1.
