PCM6240 driver implements a flexible and configurable setting for register
and filter coefficients, to one, two or even multiple PCM6240 Family Audio
chips.

Change in v7:
- Use _MAPLE as cache_type for new devices, it's a more modern design with
tradeoffs that work better for most current systems.
- Rewrite error checks to return immediately on error in pcmdev_dev_read,
pcmdev_dev_write, pcmdev_dev_update_bits, and pcmdev_dev_bulk_write,
that way there's less indentation and fewer paths later on.
- Add profileid check in pcmdevice_set_profile_id, if invalid, set to
max-value or 0.
- fixed the return value as -EBUSY in pcmdevice_startup
- remove unused chn and chenend in pcmdevice_select_cfg_blk
- Be consistent with name, ret, rc, err.
- fixed compiling warning on iteration 4 invokes undefined behavior in
pcmdev_regbin_ready.
- remove unnecessary blank line between
"module_i2c_driver(pcmdevice_i2c_driver);" and
"static struct i2c_driver pcmdevice_i2c_driver".
- Move reset into i2c_probe and remove sw_rst callback.
- extract the put_vol and get_vol function as pcmdev_put_volsw and
pcmdev_get_volsw to reduce the red
- Simplify and rewirte gain_control_add code.
- Move gain kcontrol into codec_probe.
- Unified ret and rc to ret.
- correct of_gpio.h to gpio.h
- Add an array pcmdev_ctrl_name to store the gain control name.
- Move i2c_set_clientdata before sw_reset.
- Remove pcmdevice_startup, it seemed unnecessary once firmware_request was
move to i2c_probe.
- Add return value into pcmdev_profile_ctrl_add.
- If one side of the if/else has a braces both should.
- mixer-test kselftest to check the Kcontrol
- follow the same convention for error log
- Add sound-name-prefix for bin file name and control name
- use get_unaligned_be16 instead of be16_to_cpup and get_unaligned_be32
instead of be32_to_cpup for potentially broken alignment
- remove gain kcontrol for each device
- send the output of mixer-test from a machine with this driver in it as
part of the cover letter, it'll make it easier to tell what's going on.
