[PATCH] ALSA: hda/realtek: Fix speakers on ASUS ROG Zephyrus G14 GA403UM

[Garrett Blackmon]

The GA403UM (SSID 1043:1044) uses the same ALC285 codec + dual CS35L56
I2C amplifier topology as the GA403U and GA403W variants, which already
have quirk entries (1043:1b13, 1043:1024). Without the quirk, the
woofers sit on a separate DAC from the tweeters, so the hardware volume
control only scales part of the speaker system and the headset
microphone pins are not configured.

Apply the existing ALC285_FIXUP_ASUS_GA403U_HEADSET_MIC fixup to the
GA403UM as well.
