  Move tas2563 from tas2562 header file to tas2781 header file, because
tas2563 only work in bypass-DSP mode with tas2562 driver. In oder 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 dooes is to parse
the firmware and download them to the tas2781 or tas2563, then power on
tas2781 or tas2563. So, tas2781 driver can be resued as tas2563 driver。
Only attention will be paid to downloading corresponding firmware.

Change in v3:
 - Move tas2563 to tas2781 driver
 - Add more comments on why move tas2563 to tas2781 driver
 - Provide rationale in terms of bindings and hardware, not in terms of driver.
   Or at least not only.
