In glk when device boots with only 1366x768 panel, HDA codec doesn't
comeup.
This result in no audio forever as cdclk is < 96Mhz.
This change will ensure CD clock to be twice of BCLK.
v2:
- Address comment (Jani)
- New design approach
v3: - Typo fix on top of v1

Hi Ville, Jani,
Since right version of this patch is taking time(doing modeset and
cdclk bump) as we need to poke sound driver. Can we please get this
v3(same as v1 with typo fix in comment) version of patch merged.
This works all the time and will unblock Audio and lot of folks. without
this patch audio card is not getting detected at all and blocking basic
audio feature.
Regards,
Abhay
