Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board.

Add links to the binding documents for the new sound and hardware
monitor parts of the driver.

Since there are more IOT2040 variants with identical hardware but
different asset tags, the asset tag matching should be adjusted to
support them.

For the board name "SIMATIC IOT2000", currently there are 2 types of
hardware, IOT2020 and IOT2040. Both are identical regarding the
intel_quark_i2c_gpio. In the future there will be no other devices with
the "SIMATIC IOT2000" DMI board name but different hardware. So remove
the asset tag matching from this driver.

The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.

Let's add that possibility.

I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:

twl6040 0-004b: Failed to write 2d = 19: -121

And then any following register access will produce errors.

There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.

To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.

Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.
