The ta2563 is a smart amplifier. Similar to tas2562 but with DSP. Some
Lenovo laptops have it to drive the bass speakers. By default, it is in
software shutdown state.

To make the DSP work it needs a firmware and some calibration data.
The latter can be read from the EFI in Lenovo laptops.

For the correct configuration it needs additional register data.
It captured after running the Windows driver.

The firmware can be extracted as TAS2563Firmware.bin from the Windows
driver with innoextract.
https://download.lenovo.com/consumer/mobiles/h5yd037fbfyy7kd0.exe

The driver will search for it as TAS2563-17AA3870.bin with the 14ARB7.

It uses the default program/configuration, and has no controls for these yet.

The amplifier works without firmware, but I don't know how safe is it,
that's why the firmware is required.
