Subject: [PATCH] ALSA: hda/realtek: Amp init fixup for HP ZBook 15 G6

HP ZBook 15 G6 (SSID 103c:860f) needs the same speaker amplifier
initialization as used on several other HP laptops using ALC285.

This commit also adds a new "alc285-hp-amp-init" model that can be used
to apply this same amp init fixup to other devices by passing
"hda_model=alc285-hp-amp-init" to the snd-sof-intel-hda-common module or
"model=alc285-hp-amp-init" to the snd-hda-intel module, depending on
which is being used.
