Bug description:
[Impact]
No audio output for the cs35l56 amplifier on HP LAPZ16 series laptops.
[Fix]
cherry-pick from upstream commit of linux-firmware d2b574154896 ("cirrus:
cs35l56: Correct filenames of SSID 103c8e1b and 103c8e1c") to correct the dsp
fw name to be loaded for particular SSIDs.
[Test]
1, Boot up the LAPZ16-PV-SKU3, LAPZ16-PV-SKU4, LAPZ16-PV-SKU5 with audio SSID
DSP system name 103c8e1b.
2. Play audio with `speaker-test -c 1`
3. Verify the audio play correctly by hearing and the volume is expected.
[Where problems could occur]
The fix is only for particular SSID w/o impact to other machines.
