Subject: [PATCH 5.4 93/98] ASoC: Intel: Skylake: Enable codec wakeup during chip init

From: Cezary Rojewski <cezary.rojewski@...el.com>

commit e603f11d5df8997d104ab405ff27640b90baffaa upstream.

Follow the recommendation set by hda_intel.c and enable HDMI/DP codec
wakeup during bus initialization procedure. Disable wakeup once init
completes.
