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.

## Known Issues
- No audio output when using a headphone
- Cannot get the mainboard serial number from the mainboard: the OEM
UEFI firmware gets the serial number from an "emulated EEPROM" via
I/O port 0x1630/0x1634, but it's still unknown how to make it work
