On Geminilake, sometimes audio card is not getting

Geminilake. HW codec and HD audio controller link was going
out of sync for which there was a fix in i915 driver but
was not getting invoked for GLK. Extending this fix to GLK as well.
Tested by Du,Wenkai on GLK board.
Bspec: 21829
v2: Instead of checking GEN9_BC, BXT and GLK macros, use IS_GEN9
macro (Jani N)
