This adds a devicetree configuration for Raspberry Pi 4b connected to
Cirrus Logic Lochnagar 2 audio development board and CS47L15 codec.
The common (codec-independent) Lochnagar 2 configuration is separated
into a dtsi to simplify re-using it for other codecs.

under the clock framwork because they are I2C/SPI-connected peripherals
and access to the registers would cause a nested get of the I2C/SPI bus
clock. The clock framework does not support this and it would result in
a deadlock.

This adds the two new properties 'plls' and 'sysclks' to the dt bindings.
These add the ability to set values that will be
passed to snd_soc_component_set_sysclk() and snd_soc_component_set_pll().

Sadly I don't think creating a new device tree is a good solution here. If we

Info on the codecs is available from www.cirrus.com.
The Lochnagar audio development board is not a hat, but it can be wired
over to the RPi GPIO header. It is not specific to the RPi.

ering interdependencies between components. The
plls and sysclks are applied to a component as it is passed to the card
set_bias_level/set_bias_level_post callbacks. It follows from this that the
order components are configured is the order that they are passed to those
callbacks.
