Iru Cai 871f62c376 lenovo/t440p: Add HDA verbs from the OEM firmware
To get the HDA verbs from the OEM firmware, open the firmware with
UEFITool, search for the existing HDA verbs, extract the UEFI module
and look for the verbs. Copy the consecutive 4 dword sets that look
like HDA verbs.

It is tested to make audio output from both the speaker and headphone
work.
