[PATCH v2 8/9] ASoC: Intel: avs: Power and clock gating policy overriding

[Cezary Rojewski]

Provide pgctl/cgctl_mask module parameters for overriding power and
clock gating policies respectively. These help deal with rare firmware
loading failures on some configurations. There're no golden masks that
cover all known problems so leave the defaults as is.

While at it, update avs_hda_l1sen_enable()'s definition so it aligns
with its power/clock friends.
