[PATCH 6/7] soundwire: intel_ace2.x: power-up first before setting SYNCPRD

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

The existing sequence is fine if we want to only use the xtal
clock. However if we want to select the clock, we first need to
power-up, then select the clock and last set the SYNCPRD.

This patch first modifies the order, we will add the clock selection
as a follow-up.
