Move tas2563 from tas2562.yaml to tas2781.yaml to unbind tas2563 from tas2562 driver code and bind it to tas2781 driver code, because tas2563 only work in bypass-DSP mode with tas2562 driver. In order to enable DSP mode for tas2563, it has been moved to tas2781 driver. As to the hardware part, such as register setting and DSP firmware, all these are stored in the binary firmware. What tas2781 drivder does is to parse the firmware and download it to the chip, then power on the chip. So, tas2781 driver can be resued as tas2563 driver. Only attention will be paid to downloading corresponding firmware.

The TAS2562 is a mono, digital input Class-D audio amplifier optimized for
|
|
efficiently driving high peak power into small loudspeakers.
|
|
Integrated speaker voltage and current sense provides for
|
|
real time monitoring of loudspeaker behavior.
|
