[PATCH] soundwire: qcom: remove unneeded check

[PATCH] soundwire: qcom: remove unneeded check

[Steev Klimaszewski]

commit 1fd0d85affe4d6 ("soundwire: qcom: Add flag for software clock gating check") 
added a flag for software clock gating check, however in commit
33ba01788889666 ("soundwire: qcom: Add support for controlling audio CGCR from HLOS")
the same check was added without the flag, so we would still end up failing
the software clock gating check.

Originally reported by Amit Pundir on DB845c, I also saw it on the
Lenovo Yoga C630, right before the splat, we would see

qcom-soundwire wcd934x-soundwire.6.auto: Failed to get audio_cgcr reset required for soundwire-v1.6.0

however, SDM845 has a soundwire-v1.3.0

Since the flag was added in 1fd0d85affe, lets just remove this one.

Hi Steev,

Thank you for looking into this crash. Srini submitted the same fix
earlier this week

Oh perfect, I'm not sure how I missed that when I was searching.  This
can be abandoned but it's nice to know I got the fix right :D
