Subject: [PATCH v3 2/5] ASoC: tas2562: move tas2563 from tas2562 driver to tas2781 driver

Move tas2563 from tas2562 driver to tas2781 driver, 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 from tas2562 driver 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.
