SRU Justification:

[Impact]
New HP platform with Realtek ALC3315/ALC3247 audio solution (w/ or w/o TI Amp TAS 2783A) fail to toggle the speaker/mic mute led accordingly while the speaker/mic mute function work w/o problem. This SRU includes fix for the following platforms
LampasW14 - HP ZBook 8 G2a 14 inch Mobile Workstation PC - ALC3315 - 8F42(TI Amp TAS 2783A)
LampasW16 - HP ZBook 8 G2a 16 inch Mobile Workstation PC - ALC3315 - 8F62 (TI Amp TAS 2783A)
MerinoW14 - HP ZBook Firefly 14 inch G2i Mobile Workstation PC - ALC3315 - 8ED9 (TI Amp TAS 2783A)
MerinoW16 - HP ZBook Firefly 16 inch G2i Mobile Workstation PC - ALC3315 - 8EDA (TI Amp TAS 2783A)
IceCream - HP ZBook X G2i 16 inch Mobile Workstation PC - ALC3247 - No AMP

[Fix]
Backport the upstream fix 9afbbf490322 ("ALSA: hda/realtek - Enable Mute LED and Tas2781 for HP platform") for the solution w/ TI Amp TAS 2783A amplifier
Backport the upstream fix 500372aeb556 ("ALSA: hda/realtek - Enable Mute LED for HP ZBook X G2i platform") for the non-amplifier solution

[Test Case]
1. Boot up the machine of new HP platforms w/ the listed SSIDs
2. Press Fn+F4 for mic-mute function Fn+F1 for speaker mute function
3. Click led lights up/down in according with the speaker/mic mute functions.

[Where problems could occur]
It adds the quirk for particular SSIDs of the audio solution. No regression expected.
